• Environment:
  Test between Android 6.0.1 with Ring version 20180201 (Nexus5X)
  and Android 7.0 with Ring version 20171215 (Huawei Tab)
  Using 2 different ring id

• Reproduce steps:

  • On Nexus5 Set to use mobile data
  • on Huawei wifi (this is the only choice because no gsm on this device )
  • Send message from Hu to Nexus user
  • It's received after a long delay (seeral minutes)
  • Send message from Nexus to hu
  • It's not received at all

But all messages are received correctly when both use wifi (on the same network at least)
