Losing all metadata on exiting app

Came to watch something on Infuse (v5 fully updated) on Apple TV 4th gen (not 4K). The library was empty. The 600+ movies and 1100+ tv episodes and metadata were missing. The search started and began to populate the library.
I left it going until it completed. Everything seems to play ok.

Came back an hour or so later. Woke Apple TV from sleep and into the library… empty again … last updated:never.

I’m in the process of deleting the app and starting again (again).

But any insight or advice welcome. At the moment it’s practically unusable

Thank you. I’ll add my voice to that one too.

So far . . . . since updating to 11.1 the metadata has stayed in place
