iPassword not working on iOS 14.6
I have been using the iPassword app paid version for years but it cannot be opened after the iOS 14.6 update few days ago. It seems the developer has removed the app from the store and I can't download it anymore. The worse thing is the developer create a new version of iPassword (now call Password manager with different logo, I post the link below) which is exactly the same as the previous one in design and functionality. I download this app and tried to restore the backup from icloud, but the new app pop up a note say that it can't restore the data from the previous version. This is so irresponsible and doggy ! Any solution to retrieve my important password?
below is the link of the new version of iPassword at app store, I am sure it is developed by the same people:
