I generate all my invoices on the phone( Android) app. It's been giving me trouble for last 2 weeks. Keeps crashing and won't compete and actions like saving or delete.

Hi there theindianexpress,

It's vital that all your transactions are entered correctly so that your books can be complete. QuickBooks Online is a great tool that allows you to access your books from anywhere with an internet connection. I can point you in the right direction for help with the mobile app.

I appreciate the troubleshooting steps you've already taken. For further assistance with errors with the app crashing, I recommend reaching out to the QuickBooks Online support team outside of the Community. They'll be able to provide further troubleshooting steps as well as collect the necessary information to notify our engineers. You can reach them using these steps:

Schedule a Callback or start a Chat: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
