Ive had something similar to that happen before the upgrade. Probably been 6 months since the last time. I’d be in the middle of an edit, I hit enter or move the cursor and it would delete everything I just typed. I’d hit the post button, then click edit again, and the original edit would be saved...but if I wanted the edited text to show up, I’d have to alter something, then click save...and what I originally posted would post. Also from an iPhone.
