We have just gone live Globally and have found that users on Android are having a very differnt experience to those on Apple.
How is it best to report the issues? For example a user who has an LG V30+ Android Ver 8.0.0 Oreo has had to delete and reinstall the app everytime he wants to use it!
Log a ticket with Concur support.
I've had hundreds of users on various Andriod/iOS versions and devices with no issues.
Are you android users using the PIN to login or are they using a password? Some of our users had issues before they added a PIN to their account.
Navigate to Profile --> Mobile Registration to set up a PIN.
There are user guides and a video tutorial here:
But, if it's beyond the scope of training/PIN, I would definitely submit a Concur help request with specific issues - logins of the users having issues and screenshots, if you have them.
