I could start at midnight on a Monday and by Friday 11 59 pm still be talking. To shorten it I find most if not all of the time the biggest hang up in my day to day is other people.
Someone had moved something in my house and not told me. The clerk at the store tells me "It's right over there." rather then giving me a better description.
Button labeling, as the other person mentioned is just as bad for android then it is for ios too.

In general, I get really fed up with applications where the developers are too lazy to label their buttons. It's one of the easiest things to do when coding, so why they do not label them especially after constant feedback is beyond me. I also hate it when they sacrifice accessibility for form; adding animations and cutesy things around the interface which make it impossible to use via voice over. Being a former animator/designer, I know that form and accessibility can work hand-in-hand for both The sighted and visually impaired.

As for getting around, I live in San Francisco and encounter quite a few issues daily when attempting to use Muni or navigate the streets. The most common issues I encounter are improperly installed tactile mats at intersections/street crossings. Normally at each corner of an intersection, there are supposed to be yellow bumpy tactile mats for each cardinal direction to help cross the street in a straight line. For some stupid reason, the engineers to install these mats get lazy and install only one curb cut that points 45° out into the middle of the intersection rather than having to curbs for each cardinal direction. Sometimes when they're actually are two curb cuts for the proper directions, they are not pointed straight at the other one across the street and are not lined up appropriately which can become dangerous when crossing the street. The locator tone beacons for street crossing signals are also a problem when the volume isn't nearly loud enough to compensate for traffic flow and you can't hear them to adjust your position when crossing the street or navigating to them to get set up for street crossings. I've contacted the traffic in engineering group here several times to get the volume raised on a common route I take, only to have nothing happen even after they say they've changed things.

Getting on subway trains can be problematic when you don't know what train has arrived at the station. There is usually an audible announcement as to what trains are coming and how long it will take to get there, but at most stations The announcement is not loud enough or is located at a part of the station where it is far away from where you have to be to board the train safely. Train operators calling out stop locations when the trains are out of the subway and on the street is also very intermittent and frustrating when you are going to a new location by your self. Sometimes you will get great bus and train operators who announce every stop clearly and efficiently, and then other drivers who don't give a crap and just expect you to know where you are at all times and say nothing the entire trip, even when prompted to do so as soon as I enter the vehicle.

Going back to street crossings, it's really annoying when there is street construction going on and The workers do not properly place safety baffles or appropriately Mark a safe route around the construction. In San Francisco, there is always construction going on, and sadly a lot of it is happening on one of my most common routes through the city. Every day, the area outside the construction zone is different, with different replaced cones and barriers that are always a surprise when attempting to do appropriate cane travel through the site. I actually almost completely walked into the construction area because someone left a fence gate open wide enough that shoreline Eng brought me straight through the entrance rather than around to continue along the fence line outside the zone.

I have a disability parking placard that I bring along when people drive me around. People who temporarily park in blue disabled zones to speak on the phone are profoundly annoying especially when we are attempting to find parking around a busy area of the city. Construction workers have also been known to dump excavated dirt or pile up construction equipment and material in blue disabled zones leaving the other parking spaces free.

These are just some of the gripes, your question will have to be more specific to get further specifics on user experience or general issues for travel.
