I exported my contacts from my nextcloud instance and imported it into my new one.
Unfortunately, some contacts would not import and there is no meaningful error message in the browser console.
I figured out that all contacts that failed to be imported had
VERSION:2.1. However, simply changing these lines to
VERSION:3.0 didn’t fix the problem.
Is there any way to convert this vcf file such that all contacts can be imported?
The strange thing is that it is a fresh export from nextcloud. How comes that the version differs between the contacts?
