I just noticed that the last contact sync with e/OS was on April 23 2025, 08:37 I have tried sync now to no effect.

Did you enable sync on Murena.io? I mean the checkbox where you state that you are aware of the risk and so on if you don’t have a backup.
That link is dead. Sync is enabled. Last calendar sync was Friday May 2. Last contact sync was on April 23. I am thinking about upgrade to a pay subscription, first I would like to know if the issue is with me or the other end.
I did see similar, but Contacts don’t sync with the “Main” murena account but
System > Accounts > Contacts.
This page has an option top right to “Sync now”. After tap this the sync date changed to the current time & date.
Yeah typo 
Murean. No intention to send you link, it just happend
Corrected it
Today it seems to work. Maybe I am just getting old and impatient.
