New tablespace in pdb not reflected in rman catalog - and not backed up!

Hello,

we have multitenant and dataguard. After creation of a new tablespace we don't see it in "rman> report schema;" even after multipe 'resync catalog', resync catalog from db_unique_name all'.

On standby it looks for ex. like this, there is no Datafile Name:

report schema;

Problem is: the tablespaces are not backed up of course, but there is no error, because the rman catalog 'thinks' it is complete, while it is not in sync with the control file.
