I just checked on my Samsung S9+ device and working fine with brave browser

You can download Enpass 5 which support DataVault Pwd manager import and later on you can take backup of Enpass 5 data and restore into Enpass 6. Download link: https://www.enpass.io/support/where-can-i-download-older-version-of-enpass/

Instead of doing all these messes up steps why don't you make Chromium as your default browser and then enable sync.

I think Enpass 6 supports importing the data only the latest version of 1Password (probably v7 not v4). Why don't you try installing the older version of Enpass and then try importing 1password data and later on you can take the backup of Enpass 5 data and restore into Enpass 6? https://www.enpass.io/support/where-can-i-download-older-version-of-enpass/

That's great @Vikram Dabas
