We hear about this problem every now and again, so we thought it would be helpful to line it out here.
WallaBee only sends push notifications to one device per user. If you have logged into another device other than your main device, that secondary device will receive all push notifications for your account.
For example, if your main phone is an iPhone 8 and you log in to an iPad to watch the store on a secondary screen, your iPad will receive all push notifications for your account. To bring push notifications back to your iPhone 8, log out of your account on the iPhone 8 and log back in.
