Hi,
Just in case someone needs these info!
I was running 4.6.2 but couldn't get it to work with my new 7x Pro so I decided to upgrade.
I did it from inside Basecamp app but it messed up my collection.all up.
Then I tried to restore from a backup but same thing.
After several attempts what worked was:
Uninstall Basecamp 4.6.2.
Download and install Basecamp 4.7.5.
And here comes the trick part: you need to use "Restore from previous version" in order to not have your collection all messed up!
My take: Basecamp should have only one "restore" option and be able to identify the backup type.
Best regards:
PS: 4.7.5 do work with Fenix 7x Pro.
