Since the app update, I haven’t been able to view other devices shared that I was able to before.

How to be able to access shared devices previously able to view before app update?

This can happen if the primary account holder has updated their in-app experience to the new version but the shared user has not. For the granted access user to move to the latest in-app experience, they should see a banner at the top of the devices tab that will trigger the migration. If they do not see the banner, try tapping the "+" in the top right corner of the Arlo app and select a Pro 5 camera as if you were onboarding a new device. This will prompt the app to update to latest user experience.
