This is caused by a recent switch to vCard 4.0. The solution is to either limit exports to vCard 3.0 or allow users to choose.

OK thanks
How can I do that, limit export to vcard 3.0 or allow user to choose ?
No such things in parameters.

I didn't mean an in-app solution. A code change is required.

User choice seems the most appropriate thing to do

I also have issues sharing contacts via signal. Signal will show all data in the preview, but as soon as I say "add new contact", it will only add the person's name and the very first datum (e. g. first telephone number). Do you think this is related? I cannnot find issues regarding the use of vCard 4 on the signal repo though. Thanks!
