Hello,
Just to say a customer of ours went across this issue, I found this topic with no solution, so I'm sharing what I foud:
It turned out they were logging in using a simple user rather than their main customer account, therefore they didn't have the permission to manage SSL certificates.
So in the end, this issue occurs because SSL It icon shows up while it shouldn't.
That is something to report to them.
If anyone knows where to report it, please provide the information to me so that I report the issue or report it directly if you will.
Best regards
