Configure Cloud Access under FW 5.03.103 each user configuration interface still updating
Cannot invite a new user
Cannot use Mobile App and Web App
No Notifications Email
All the problems were solved after do a system only restore.
Root cause: I imported the older version of the backup config file before, which caused Cloud Access hang up.
I too once had an issue with confused user accounts. I suspected I was moving too fast adding multiple accounts faster than the system could adsorb the changes. Another possible problem was that I tried to have two seperate users with the same email address.
I resolved the resulting issues with a system only restore. Yes - - -I had to reset all the user accounts; but all the shares and all the data was intact. A fairly easy process.
(easy if you have only a few user accounts. . . . but if you have dozens of user accounts. . . I suspect you are not using a WD NAS.)
