Zoom Rooms signage content that requires local caching like indexedDB

At some point in the last year, the browser used to play url based content in zoom room’s digital signage content has stopped persisting storage used on each playback.
This results in registration information for our html based digital signage player being lost every time the signage content is stopped while the room is in use.
When we first ‘certified’ zoom as a player for the signage software this registration information which is stored in indexedDB was persisted but now it is not.
Any help or insight would be appreciated.
