I've set up several flows for a couple of spreadsheets in order to automate one of our internal submission processes, while these flows were working for the majority of this year, they've stopped appearing in excel as of today.
The flows themselves haven't changed and the users using the flows (myself included) are on the flows as run-only user / owner but when any of us go onto the sheet and try to use the flow we get prompted to "Create a flow", currently I've had to run the flows from the my flows section on power automate.
