Well i was just trying to re-sign into Flow (Power Automate) and well this happened:
Now it first told me there was an error while signing in, yes i had to refresh the website.
After that I was logged in, but that "Message"/"Site" was still being displayed, even after refreshing the page, again with ctrl+shift+r.
Did not find a suitble place to post this, but wanted to let everyone know that this is a thing.
