Dear S. Brown,
thanks a lot for you attempt to solve my problems. This week I installed the latest firmware version 5.07.118. But also this firmware has some major bugs. Indexing became much faster but cloud access is still a problem. Today I tried to invite another user. The first welcome email was sent successfully, the user created a new OS5 web account but finally it failed (“user rejected”). Another trial to re-send the invitation email failed. It is some kind of time-out at the dashboard. Now there is a new OS5 user account but no NAS is assigned to it.
The change to OS5 really became a nightmare.
Pleas let me know what kind of protocols you are asking for and how to acquire them.
