After sucessfully running MyCollections on both my iPhone and my MacBook Air (M1 2020 & MacOS Monterey Ver, 12.0.1) I experienced a problem when syncing from my MacBook.
The Sync just 'hung' with the blue progress bar just showing about at the left hand side.
No matter what I did, (force quitting, closing down the MacBook and restarting) it always resumed at the same point.
In the meantime however, the iPhone version continued to operate perfectly and changes to the data fields, edits, adding new records and syncing worked and continues to work perfectly.
I then deleted the App from my MacBook and downloaded it again from the AppStore via your website.
On loading the App it now creates a blank screen per the attachement
I then deleted the App a second time, closed down the MacBook, restarted it then downloaded and installed the App again.
On running the App I get the same blank screen.
This has me baffled, can you please assist?
