Hi,
I strongly suspect this is the same issue (block on the server) as was experienced on this question and other similar ones.
In summary, I have requested that invites are sent to seven users' email addresses and the toast notifications suggest an invite has been sent but nothing has been received.
Repeat invites have been requested and plenty of time allowed for them to arrive, but nothing appears in the inbox. Spam and Junk folders have also been checked.
Could some kind soul take a look at let me know what needs to be done, please?
Thank you!
