Hi there! I’m just going to slightly one up op’s question: In my case I do actually add contacts to the Contacts app and still end up with the same situation as OP: contacts appear in the menu but not in the app, presenting this (possibly unrelated?) error in the console:
addressbooks.js:399 TypeError: Cannot read properties of undefined (reading 'find')
at dist.js:1:143436
at Array.forEach (<anonymous>)
at A.value (dist.js:1:143145)

at Generator.next (dist.js:1:81214)
at Ca (dist.js:1:200311)
at o (dist.js:1:200517)
In my case, I’m actually the admin (I’m self hosting), so I might be able to provide more information if needed ^^
