Community keeps on loading after Edflex catalog synchronisation

Summary:

We are synchronising the Edflex catalog to a Private community, which means that more than 1000 courses have been synchronised in the past 24 hours.

If I access the community catalog from Admin I get the message you don't have access to this learning item and if I access the community from Learner page it keeps on loading.

It worked fine with a limited number of courses for test.

Any suggestion what we're missing?

Thank you!
