it would be good to be able to attach a copy of a file in Teams (source onedrive) rather than just sharing the link. It seems that if the file to be transferred is on onedrive, one can only share the link to it rather than send a copy. it would be good to have the choice, similar to what happens with emails in outlook
@Cecilia, maybe you could reword the Title as "Attach files to a chat as files, not as Onedrive links"?
From a user perspective the file sharing in Teams is quite messed up. As a user I expect that the recipient will get a copy of the file, not a link to a file. There should be an option to send a link to a file (e.g. to keep people access the updated versions of the file), but at the moment access right issues can make the file sharing through Teams app complete dysfunctional.
It seems something has changed ~month ago and I cannot access anymore files send to me over the chat unless the sender is giving me access right to the file (in addition to Drag-and-dropping it to the chat window)
