Control file NOT current on Standby database

I am running a principal and standby on different servers running RH7 and Oracle Enterprise 19.10

After creating the standby database I am setting an rman backup level1 to run once a day Mon-Sat, a level 0 for Sun; I have set archivelog backups delete all every three hours every day.

I am getting the following errors after a:

report schema;

RMAN-06139: warning: control file is not current for REPORT SCHEMA

The archivelogs are being backed up but not deleted eventhough they have been applied.

RMAN> connect target /

connected to target database: OEMREP (DBID=3682633605, not open)

RMAN> backup archivelog all delete input;
