Case sensitive in Tags
The names of the Tags will automatically change to lowercase when tagging SQL Servers and Data Factories which causes inconsistency in Tags. Please consider case sensitivity in Tags or NOT automatically changing to lowercase to all resources.

I agree with Stanley's comments, and actively promote treating all tag names WITHOUT case sensitivity. Pick case insensitivity, and apply it everywhere.

Similar problem between portal and Powershell: the portal (mostly) treats Tags as case insensitive, while manipulation of Tags from Powershell is case sensitive. Make your mind up about how to treat Tags and stick to it...
