Notifications for the Tapatalk should work fine. I'm not having any issues with it. Having said that, go ahead and try uninstalling and reinstalling it. In regard to the iMore Forums app, an updated version was in the works and awaiting Apple approval. Whether that's still the case, I cannot say. With that in mind, past notifications issues with the iMore app were often resolved with the installation of an updated Tapatalk plugin from iMore's side. An email message will be sent to the network mods on your behalf, but being that mobile nations are preparing for tomorrow's start of CES2015, I can't say how soon this issue can be resolved.
