Hi @Kay_M_Scarbrough , @Sam_Sayer , welcome to the forum
I appreciate your frustration! The inability to sort projects in a custom order in the Team page is also driving me nuts. The newly forced alphabetical sort also affects how Projects are sorted within the flyout menus of Teams in the sidebar too.
This is not exactly related to the topic of this thread, so if you want to add your voice and your vote, then best to do so in this thread:
The current workaround is to ‘Pin to top’ all projects which will enable the drag handles on the left so you can sort your projects in custom order, again. Obviously, not ideal if you have numerous projects!
