I'm very new to Sharepoint and I have recently just moved our Classic site (which was only a year old) to Modern pages on Sharepoint Online. It's going very well, but managing users and permissions and access is a real pain.
I created a SPUSERS-ALL 365 group and I tried to share my hub and attached communities via this group and nothing happens. NO ONE gets access to the hub or any of the attached communities. I only have luck adding all the users entering them individually on each community and the allowing them access.
So I have two questions:
1. Why isn't my group working?
2. Is there an easy way to see who has been given access to a community?
