Should I reinstall the app for error HTTP Status 400 - Bad Request mean?

Hi there, @wemovedmv,


The error HTTP Status 400 - Bad Request comes up when the connection to connect with our server, was interrupted or corrupted. Let's make sure the error is fixed so you're able to use the app without any issues.


Yes, you can uninstall and reinstall the app to update it's version and download critical fixes to resolve connection and compatibility issues. Reinstall the app through this links:

If all else fail, I recommend contacting our Phone Support Team. They can open an investigation about this unexpected hitch and run some diagnostics to fix the problem.
