Pro version not active

[2uk 0]

I purchased the enpass pro version on my Apple mac and its runs ok.

Also synchonised with my Sony Android Z2 no problem so far. Synchronising from Google drive.

Now I changed phone from Android to Apple Iphone 6 iOS 11.2.6.

Downloaded Enpass from App-store and started. 

Choose : Known User.

Choose restore from Google drive.

Restore works but Enpass does not recognize me as Pro user.

I am restricted for 20 items. 

I tried also Upgrade Enpass -> Already purchased. The little wheel keeps turning ( internet works well) and does not accept my request.

What to do to get my pro status back on my Iphone?
