My own bad experience was when they rushly announced the death of third party apps. I tried to give the official app a try back then, used rif since 2012 before.
I couldn’t even log in due to an error. The app was deleted minutes later and with the API-kill I moved to lemmy.
It was the first that popped up back in 2012, when I got my first smart phone. It stayed by my side till the end. RIP rif 🫡
