Let's perform some troubleshooting steps to get this issue sorted out. We can clear the apps' data to remove the stored cache. This can cause unusual behavior in the system.
For Android phones:
For Apple phones:
If the above step does not resolve the issue, please uninstall and download the app again. Reinstalling the app ensures that you're using the latest version and willl help get you back to business.
Once done, you can try to create a dummy invoice and sent it to your personal email to see if you encounter the same behavior.
Please feel free to leave a comment letting me know how things go after giving this a try.
Thanks for getting back to us.
Have you tried using a web browser on your phone like Google Chrome or Safari when trying to create and send an invoice? This is to isolate if the behavior you've encountered using the mobile app is the same as when using the web browser.
Also, we currently support the Android operating system 4.1 and greater and iOS 9.3 and greater. Kindly check the OS and mobile app version you're using if it is up to date.
If the issue persist when using the web browser on your phone. We'd recommend contacting our Customer Care Team to further check the behavior encountered.
Message us back if you need more help with invoicing. Have a nice day!
