Absa banking app not up to scratch.

Absa, I have been a client for 30 years. Thank you but I have now taken my business elsewhere. You need to sort out your Banking app. In times off need it freezes. Very frustrating. Mostly month end I can't log in. I have the latest version. I have installed it & reinstated it. With no joy. Just thought I would bring it to your attention. Thank you.
