Moving away from Google Message after a long long time... Did miss a few of the message lately with the other party also using Google message and sent them as chat while there was no data on my phone... The main reason for me finally switching out from Google Messages is: got a new transient number, ported the new number to my old number from network provider but can't change it on Google Messages chat feature, did try find out some other people with the similar problem but no answer to it... Happy to get it touch with devs or support team to resolve this issue.
