just 1hr ago (1 AM local time) I saw 'your app is live on app store' notification on my phone and eagerly launched it... only to have it crash instantly. After a debug session I discovered an obscure bug in tflite library that only shows up in release builds. 20 minutes ago I pushed a hotfix with an expedited App Review request, hoping to spare as many users as possible from that crash. I can't wrap my head around how the appstore review missed it, especially after rejecting our last build 4 times over a barely legible location-permission alert description.
That said, I built my first mobile app 15 years ago, and to this day, building for mobile remains the most frustrating part of my programming life.
