Guest sees page for 2 seconds then access denied to Group SP site

I'm seeing what I think is the same issue for a guest user - when initially added to the Group, checking their effective SharePoint permissions, it all looks fine - then a couple of minutes later, their effective permissions include a long list of 'Deny' entries.

Did you get anywhere with this. Sounds like the exact issue I have been experiencing for months.

Thanks

If I recall correctly, in our case it was because there was a SharePoint level domain whitelist applied to the site, and the user had changed domain - so their old UPN was included in the whitelist, but their new UPN was not. We simply removed the whitelist in this case, and the issue went away.
