I'm not seeing any reports of a similar issue, so let's try some troubleshooting steps to get you back to business. These steps will reset the app back to its defaults to test for any issues.
Android: From your device's Settings, select Apps (varies by device), choose QuickBooks app from the list, and then Storage. Finally, clear data.
iOS: From your device's Settings, select Setting General iPhone Storage and choose an an app that's taking up a lot of space. To free up the storage without deleting the documents and data for the app, select Offload App.
Once this is done, re-open or re-download the app and login to see if your issue has been resolved. If it hasn't, I recommend trying the further troubleshooting steps found in our Quick Start Guide for Mobile.
Keep me updated here, I want to ensure your success. Hope you have a wonderful weekend!
