Windows phone to tablet Sync

[mouldywhale]

Hi!

Just wondered if anybody could help me with a quick question, i have my windows phone synced with my windows 10 tablet which is great, my only issue is that when i receive a Facebook messenger notification on my tablet, it first shows it as received from the phone and then again a few seconds later the messenger app on the tablet shows the same banner message, same sound - so i basically get it twice on the tablet for some reason and i don't really want that to be happening. does anybody know how I can keep getting phone notifications on the tablet but stop the repeating Facebook messages?

Thanks in advance.
