Disappearing contacts on version 1.12.3 when using Signal app

[tcecyk]

never ran into this with Signal and one cloud synced Addressbook - but you’re right, there are other reports:

• Signal deleted all my contacts - including on murena.io
• Problème synchronisation liste contacts avec app Contacts et Signal
• Contacts not working with Telephone, Message, Signal (3)

I believe, the contacts on my phone keep disappearing. They are replaced by few in signal that I have which match phone numbers in my phone.

What is the default addressbook for new contacts (see Screenshot in issue no.3) ? is it the internal AB or a cloud synced AB? and which ones are allowed to be shown in the Contacts app?
