Hello @Felke, Ariane
Welcome to Q&A forum
I have tested in Microsoft Loop for your concern, and I want to share the information to support you about it:
In Microsoft Loop, I have a personal workspace called “My Workspace” and an additional one named “Testing Space.” Loop 1 and Loop 2 are two pages within the Testing Space.
1/ To rename a page, click the three-dot button next to it, as shown in the first image.
2/ To rename a workspace, click the "Loop" symbol to view all workspaces, then select the three-dot button next to the desired workspace and choose “Rename.” Please note that “My Workspace” cannot be renamed because it is a default workspace created by the system.”
Hope this information will be helpful for you.
Even though I’ve tried to make this as close as possible to your experience, we may be in different testing environments, and I might not fully understand your needs. Please feel free to contact me again if you still have any concerns.
