[Bug] Stuck at a gray screen or crash the application when there is an error from the API on Login page

[minhnimble]

Issue

When the user provides an invalid combination of email and password, there is no handling or a visible prompt on the application to let the user know what is currently happening. Instead, the application just show a gray screen and stuck there forever.

When attempting to log in to the application without any connection, it actually crashes the app.

Expect

Error cases should be visibly handled on the application and let the user know what is happening.

Steps to reproduce

• Provide an invalid combination of email and password:
