I have sent this info to DigitalSignage support sew weeks ago but I see they don't care about it (I didn't receive any answer).
I have Enterprise account and few signages installed on different accounts. I have noticed a few weeks ago that notifications are not working anymore (when a player is offline). I have the same situation on every account.
Everything was fine a few weeks ago.
Dis you notice the same?
Best regards,
arcos
