I have an app that calls a couple of flows, and everything has been working fine until yesterday. When I try to refresh flows that have already been added, I get an error saying that... flows added via old pane cannot be refreshed...and need to be re-added manually.

I can't add new flows either. It says that I don't have any instant flows, which is not true either:

I could create a new flow, but it won't give the option of creating PowerApps(V2), only PowerApps. Is there something going on with the PowerApps platform? All the app, flows are within the same environment, I haven't done any changes to the app.
Thanks for any help.
