Steps to reproduce the bug

1. Contacts are integrated via various accounts via CardDAV.
2. Open one of the mentioned apps or a tab within one of the mentioned apps that accesses the contacts.
3. The list of contacts is loaded.

Expected behavior

The contacts are loaded (with a slight delay).

Actual behavior

Screenshots/Screen recordings

No response

Additional information

This is a particular problem with incoming calls if the number is stored in the contacts but the contact is only displayed with a delay or not at all during the call process. The caller may hang up prematurely or be redirected to voicemail.

Over 5,000 contacts are currently integrated. This number is gradually being reduced by merging contacts.

I originally mentioned this phenomenon at FossifyOrg/Phone#127.

You are right.
There was a problem when the report was first submitted.¹ The title and the selection of the affected apps were deleted. I didn't notice the latter. Thank you for pointing this out. I have updated the description.
