The android share menu is a menace.
It got far better on…version 12 and newer I think it was. Some parts of the share menu still seem fairly random like who it suggests you might want to share with. But they’ve at least locked in where “copy link” and a few other things are so they’re consistent.
I’m on version 12 and it still seems completely random. I use QKSMS and it persistently tried to put my boss and extended family’s SMS quicklinks at the top of the sharing menu, so I had to download a program called Watt and disable QKSMS’s sharing module manually to stop it from happening. If it could just deterministically let me enable/disable and/or sort the sharing menu I wouldn’t have to live in fear of it.
