Hi Garima !
1. Here is the link to the Banking Mobile app : https://play.google.com/store/apps/details?id=net.banqueatlantique.mbanking
2. My android is version 10
3. I noticed this morning that the Android auto-fill was enabled after the software update, so i disabled it and let auto-fill accessibility only enabled then try the Bank application and it works fine like before. So i suppose that the issue is with the Android auto-fill.
Thanks,
