Ring Video Doorbell on Echo Show on separate Amazon accounts

Hi,I’m the owner of the Ring video doorbell. I added a shared user who has a separate ring account. Both of us can view the video doorbell in our respective apps. Both the shared user and myself have separate Amazon accounts which are both linked to our respective Ring accounts.I have 2 Echo Shows. The Ring Video doorbell works fine with one Echo Show which is my account (both Amazon and Ring account). The second Echo show is in the shared user’s Amazon account and Ring account. However, I am unable to view the video doorbell in the second Echo Show. I receive the following message on the second Echo show: ‘You don’t have permission to view Ring cameras on this device. The owner of the camera can update permissions from Control Center in the Ring app’.I’m the owner and the permissions look fine for me and the shared user. All apps, Ring, Alexa and Echo devices are all updated with most recent software fixes.Am I doing something wrong here? Is there a fix for this?Thanks in advance for your help.
