I bought Simple Contacts Pro, it's great but it has enough papercuts to where I went back to True Phone. Here are my bug reports:

Set default phone number for contact: https://github.com/SimpleMobileTools/Simple-Contacts/issues/...

Cannot create new group (category) for Nextcloud account/address book: https://github.com/SimpleMobileTools/Simple-Contacts/issues/...

Favorites tab showing contacts from all accounts: https://github.com/SimpleMobileTools/Simple-Contacts/issues/...
