I was shared a workspace that was part of a realm.
When the workspace was shared with me, I wasn't part of the realm.
At that point, in the "Sharing..." screen my name had "Pending..." by it (see attached) and I did not see the workspace in my workspace listing.
However, I was later added to the realm.
After being added to the realm, my name still had "Pending..." by it and I was not able to view the workspace and it was not in my list.
I next suggested to "unshare" the workspace and then "re-share" it. At that point, after sharing the "Pending.."went away and I was able to enter the workspace.
I have a request for enhancement that in such situations maybe either 1) not letting the share "go through" so that I'm not added with a "Pending..." so that no "un-share-followed-by-re-share" has to be done, because the requirement to do that for successful share might not be noticed or 2) once I was added to the realm, the "Pending..." should have been removed and I should have been able to enter the workspace.
