I had the UBS Access App installed from Aurora Store, but since December 2022, it needs an update and the update was missing from Aurora Store.
So, the only way I found, is:
1 . go to https://appgallery.huawei.com/
2. search for “ubs access”
3. on https://appgallery.huawei.com/app/C103690961, click install
4. then click on “Install AppGallery”
5. install the Huawei AppGallery
6. install/upgrade the UBS Access App
7. de-install Huawei AppGallery
There is surely a better way, but this worked.
