Very very frustrating and keeps happening to every time I use the app. I type full paragraphs that disaapear if I look away from the screen 10 seconds and it dims black (did not even lock phone or exit app). It haapened this time while I was reading the comment I typed before posting it. I cannot stress how awful that is and it was gone, no draft and not saved anywhere.
Please fix.
Right sidebar —> Settings —> Hide read posts switch.
See if it’s your case.
If I’m to think long about some answers, I put them in a different notes app and save post\comment, or just add edits to the end of my comments after posting it.
