Hi chilidog,
Do you recall which events you favorited to try to remove them as favorites? Any difference if you try to favorite more events from the Today's Odds back then go back into favorites and refresh the page?
The first time I favorited on Edge, the events appeared normally. Then I went to Chrome and reproduced what you saw, but as soon as I favorited a couple more events they loaded in.
We will try to debug this. Thank you for sharing and if you have any other details let me know.
