Vcard exporte from Protonmail not working by default

Hello,

I don't no why but, when a export my contacts from Protonmail (PC webmail interface) in .vcf, I can't import it on my phone "incompatible format issue" I finally found a free app for import it (on APKPURE : https://apkpure.com/fr/contactsmanager/com.ihubin.contactsmanager) On the app in "About" section, all bricks seems in OpenLicence

I attach a test contact, if you whant to test: 1._TEST.vcf

I don't konw is I'm the only one with this issue, but if not, fix it without additional app can be cool :)

Have a good day !
