SharePoint Home: Stale results in followed sites - Graph not able to remove

Hi,

I was wondering if the following behaviour is the same for you guys regarding followed sites in SharePoint Home:

For me, sharepoint.aspx still shows site collections under "Following" that do not exist any more. Well okay, they exist in the SharePoint admin center recycle bin but this shouldn`t be the reason why they`re still being followed, or is it?.

I thought I could remove them programmatically through the Graph beta endpoint described https://docs.microsoft.com/en-us/graph/api/site-unfollow?view=graph-rest-beta&tabs=http.

Unfortunately, this does not do anything because I`m constanstly getting 207 with no error message.

Has anyone ever attempted this before? Thanks for your help.
