I apologize the inconveniences and will try to help you the best possible.
#3 is a known bug, and solved in the Upcoming version of CRED
It's a wrong Link (to an not yet exciting part of the Dashboard of Access)
#2 sounds serious, but I don't know how to reproduce it,
locally and on other Sites, updating ACCESS did not produce this issue.
#1 Also is not a agreeable situation, as well, I can not reproduce it
We must separate the Topics.
You can choose whether to stick on #1 or #2, but I can not handle Both issue here
In any case, if you have a System where you have the old Toolset (working) installed, can you create Snapshot of it, and send it to me?
We usually recommend the free Plugin "Duplicator" for this porpoise.
If you already know how Duplicator works
(http://wordpress.org/plugins/duplicator/),
please skip the following steps and just send me the installer file and the zipped package you downloaded.

Send me both files (you probably want to use DropBox, Google Drive, or similar services, as the snapshot file will be quite big)
❌ IMPORTANT ❌
Remember to create or keep an admin account for me before creating the snapshot, or I won't be able to login. You may delete the new admin account once the snapshot has been built.
I will enable your next answer as private so you can provide me the information securely.
I will then be able to update and see if this also happens on my Localhost.
If you don't, can you let me know how exactly we can reproduce this problem?
As by simply updating, it does not happen.
Thank you
