AutoRemote Messages arriving twice

Hello,
Without any changes on my part, since yesterday (or maybe the day before), all my AutoRemote messages are arriving twice.
They are only being sent once - could this be something has changed the server end or in the app?
I've checked I have a cooldown set in Tasker to avoid multiple triggers and the logs certainly don't suggest any AutoRemote push is being sent twice, but they are definitely arriving twice!
Cheers,
Bill.
