To be clear: I prefer to pay for things instead of having to see ads but 13€ / month!? For a meta product that has inherently user-hostile design patterns even without ads?
Phone got stolen last year. New phone, installed instagram, tried to log into account, but locked out.
Instagram tech support told me I either had to: 1) take a photo of myself, they'd check if it matched any selfies in my account, or; 2) I had to associate my Facebook profile.
I'm security conscious enough to not post selfies online, nor use Facebook. Goodbye instagram.
Twice I've been blocked out of my account, the first time it was because I was accessing from too many different IP address (VPN). The second time.I didn't even bother to contact support and was willing to loose my account.
Also, I recall many years ago in the early days of the app there was an app update that would straight up not work on my phone and had to sideload an old apk in order to keep using it. And according to google I wasn't the only one.
Took me a few months of manually testing new updates until a newer version worked for me. Not to defend Facebook or Twitter, but a fuck up like that one would never make it past their QA teams.
