Who I have the same questioned this topic

Recently Message+ app on my desktop does not show any incoming messages, be it from IOS or Android phones.  I even uninstalled this app and installed it again, it did not help.  The same happens to Web App - does not show recent messages either.  The last message synced up is from 10/13/16.  Is there any info on how to fix it, or who should be contacted from Verizon support with this issue?
