[Help] Contacts 1.5.3, contacts missing after update

After nextcloud-Upgrade form 11.0.2 to 11.0.3 the contacts-app was deleted. I installed the newest version 1.5.3. Only a part of my contacs are available. I usualy seperate my contacts in different adressbooks like “Contacts”, “whatsapp”, “private” and “business”. But now only the adressbook named “Contacts” is available.
I have created backups of the other adressbooks, but the import icons are missing in the new version.
How can I import my other adressbooks ?

Sorry for the late reply.
Is this still occurring? Data loss is a serious problem. Do you have access to your database?


Problem was solved with the integration of the contacts-app into nextcloud !
