as your post I give you screenshot about my Edge Chromium work profile sync problem.
Step1.jpg and step2.jpg show my Edge configuration. After enabling sync I return in setting screen and nothing is changed. I have always step1.jpg and step2.jpg screen.
I attached my configuration on Office365.
Thank you a lot for your help.
@MissyQ I follow your instructions https://techcommunity.microsoft.com/t5/discussions/sync-isn-t-available-for-this-account/m-p/1250609...Have I wrong somethings?
Thank you for your help.
