Hi Garima,
I downloaded the 6.5.2. (724) version from microsoftstore. And was able to restore my data from the back up (windows).
So the issue is solved.
However there is still another issue. I also installed the newest Enpass version from Apple store on my wifes new MacAir.
When I try to restore the data from the same back up on my server, it says my masterpassword is not correct.
I checked and double checked. But the master password I used is the right one.
Do you have any clues?
Thank you.
And a happy new year.
Léon
