Same issue, only on a group text. Happened with my S7 Edge, happening on my Pixel 3A now.
Happens with users who are apple and android, one separate group of 4 and group of 3 all different numbers and carriers. I am in 62285.
Restarting, wifi, format, none of these work and since its going on with two different phones I am thinking its a Verizon problem.
