I am also having the same issues and using Google Fi on a Nexus 6P. In fact, Chomp has not worked (either immediately crashes, or fails to work normally) for a month already. Yesterday Chomp did not crash, but does not work correctly either. I can send SMS and MMS messages but definitely can not receive MMS messages. Also, the text of the messages received does not match the messages listed by the Android Messages app as if they are totally different files.
This is really sad after using Chomp without problems for seven years already (4 years on this device).
I also see a mystery green dot next to some messages. To me this suggests that there is a new message but there is not and the green dot does not go away.
