We are so sorry that you are encountering this issue. We are currently working with our Dev team to fix this.
In the meanwhile, there is a workaround that will prevent this from coming up again.
Tap on the Menu (top left)
Tap on Settings
Tap on Manage Profile
under "Update Tokens"
please fill in all information, and tap on the "save" button at the end of each line.
This should stop that page from coming up again.
If this does not work, please contact support for more information.
