Use your own domain as sharepoint site
what I want and I think that a lot off you also want this is:
When I go to let me say my tenant is choco then I must go to https://choco.sharepoint.com/sites/.... to get to my sites.
It is easier to implement that when we go to let me say https://sh.choco.online/....
where the ... is every different site late personal folder and stuff like that
and when you make a teamsite you can then choose to take the following subdomein: ts.choco.online. the only thing that is needed is offcourse that the domain choco.online is the domain you own.
