Users who have successfully joined Loop workspace get perpetual loading screen when they go to view their Loop workspaces

I'm able to invite colleagues to access my Loop workspace, and they are able to accept (when I click "Share" inside the workspace, I see these colleagues have joined; and thus i'm not able to invite them again). However, when these colleagues (who had not created any Loop workspaces themselves, so their main Loop homepage would only be expected to show the workspaces I'd shared with them) access the main Loop homepage, they get a perpetual loading screen (i.e., the purple spinning circle animation).

They've tried opening/closing tab; clearing browser cache; several different browsers; restarting their machines and re-accessing, but they continue to get the perpetual loading screen at the Loop homepage.

I've tried this with one user who has full admin access, as well as another full user who has more limited access, and the behaviour is the same.

I just made some really nice workspaces I'm very keen to share with my team, would appreciate help sharing it with them!
