synchronization no longer works for relationships

[StefanLdhl]

I updated Seam3 from 1.4.9 to 1.5.5 today.
Since then, the synchronization of relationships (-one AND -many) no longer works in my project.

There are no "References" visible in my CloudKit dashboard.

No errors, neither in the CloudKit logs nor in Seam3.
Everything worked fine under 1.4.9.

Any ideas?

Thanks! :)

It's an older post, but:

I also have problems using 1.5.6 in case of one-to-one relations. If I change the relation to one to many it works without any problems, only in case of one-to-one I am not able to get it working
