Absa app not linking to new phone

I moved to a new phone and when trying to get the Absa app to use it only gives the option to fill in my ID, do a biometric face scan and then fill in the bank account details. I did all of the above about 5 times correctly but it still doesn't want to work. It ends up telling me it failed and that I should use my ID to link my device. There is no troubleshoot option. There's no option for customer service help. Terrible app service. How can I get it to work? I see a lot of other people have the same problem.
