The latest MobiControl 14.3 is no longer saving changes to existing Profiles.
I uploaded a new Package (let's say version 2.0) then modified the Profile's Package assignment to the latest version and hit "Save & Assign". At the Save & Assign window, I basically hit the save button to keep the previously selected groups. The new UI's Profile page then shows me an older version "1.2", and the changes I applied were not actually saved (confirmed by revisiting the old UI's Profile window). Reopening the Profile's list of Packages shows me the previously selected Package version "1.5" when I had in fact chosen "2.0".
Simply choosing "Save" instead of "Save & Assign" makes no difference.
Deleting the older package "1.2" does not help; the new UI still thinks I have selected "1.2" while the old UI shows "1.5".
Now before you tell me "just create a new Profile"... I have some bad news for you.
The same problem is replicated when creating a brand new Profile with a single Package. I select the latest version (2.0) and the new UI shows me the older version available (e.g. 1.3, since I deleted "1.2" before).
And yes, I cleared my browser cache, cookies, the kitchen sink, etc.
MobiControl 14.3 also stopped supporting RSA-PSS certificate signatures (this was fixed in 14.1.x and is broken again!) resulting me to re-generate SHA2 certificates.
So yeah, probably a good idea to postpone updating to the latest and greatest until these issues are sorted.
Side note: the new Profile and Package UI reduces productivity quite a bit. Takes more clicks and more pop-up windows to delete packages. Was this "improvement" actually necessary?
