Hi, I’m having an issue with my Adalo app after uploading it to Testflight. The screen momentarily goes black, and then I’m immediately presented with the standard iOS lock screen, forcing me to unlock my phone again to continue when: 1. Querying database collections 2. Changing screens - Transitioning to specific screens that contain these database queries. The screen goes black during the transition, and I land on the lock screen. The app works fine in the Adalo preview. The phone itself isn’t freezing or requiring a force restart. The app’s action seems to crash or interrupt the iOS UI, kicking me back to the normal lock screen. Has anyone else experienced their Adalo app unexpectedly causing the screen to go black and return to the iOS lock screen during database queries or screen transitions? THANK YOU! ---

Hi @Carlotta, Sorry to hear that, I haven’t seen such issues recently. If you haven’t done so, I would advice to submit a ticket: [Right Desk](https://info.adalo.com/submit-a-support-ticket). Best, Victor. ---

Hi @Carlotta, That’s strange, usually you get confirmation email almost immediately and Adalo support answer within a few hours. @CH_Team maybe the request was lost? Best, Victor. ---

Hi Victor, interesting… I’ve submitted several support tickets but never gotten a confirmation either… @CH_Team is there another way for me to reach support? Thank you !! ---
