FeedHub: Google Shopping Feed

Generally works well. On occasion, products will just disappear from FeedHub with no warning (except from Google merchant center to advise of a sudden drop in products).

It's as if Feedhub suddenly can't see products, despite no changes being made to anything.

I can't complain too much as we're on the free plan.

Update: Tried fixing the issue for an hour, then tried support (on holiday). Have since uninstalled and tried a new app which is working fine.

Update 2: Well the new app did not have any historical product data with merchant center, which was about 4 years worth. So, I am back to Feedhub as losing that much data would be disastrous for an ad campaign. Reinstalling Feedhub seems to have fixed the issue, thankfully
