Opening the app before the last update (aug 17th 2026) bricks the app had to uninstall and setup everything again. 50 minutes on the clock wasted! My biggest issue was the app decided to stop working over night and it provided no error codes or suggestions other than "your screen is not private" when in fact it is and i spent 45minutes frantically hunting for any way my device was compromised. In the end, reinstalling worked immediately response not helpful, dont break code thats crucial!

We’re sorry for the frustration and time this caused. We’re glad reinstalling the app got you back up and running. If you encounter this again, make sure the Square app and your Android OS are up to date, close any apps that may be displaying over or sharing your screen, and restart your device.

And again. you push an update. that deems the app unusable. "can't find connected device" which there isn't one. only fix is a complete uninstall and reinstall re-login. all the while my client is standing there waiting. this is the 3rd time. all the last updates did this. it updates to an unusual app. until i redo everything. wasting my time and my clients. this is very inconvenient.

Dear Block, please let me know how to contact you to discuss this issue further. I just updated to your latest version, and it still logs me off. Hate it after the recent upgrade. Every time I pick up my phone to make a new sale, it disconnects the card reader and forces the app to reconnect to square and reload the app, even though it's still running in the background. Very frustrating. This causes a big delay when trying to do a transaction with a customer standing in front of me.
