There is an option of an unofficial install in Microsoft Store, is this safe, ok?
What is S mode worth at all, if you suspect an app from Microsoft Store not being safe (This comment should not be misinterpreted as a confirmation that it is safe)?
Yes, I understand that. But what I really wanted to know is if that install from repackagerexpress is coming from LibreOffice org, or it is another thing. I am not sure about it.
But you didn’t tell about “repackagerexpress”, and even now you didn’t mention a link.
Fwiw the only LO in MS store currently that us from an actual LO contributor is CIB. TDF has plans to come itself to the store, but not yet.
