@apps just had my first crash, but was not prompted to send a #FedilabReport via mail. I was switching a lot between Fedilab, Firefox and my calendar to look at event details and enter them in my calendar. When I returned to Fedilab, I tapped on the repost icon and wanted to continue scrolling. The app froze, I had no animation, but the icon was blue. After a few moments of being frozen, the app closed itself and when I opened it again the post was not boosted.
I'm on 3.29.2 from f-droid.
