Not receiving group texts from an iPhone 14

I have an iPhone 8 and have been in a group text with 3 Android and 1 other iPhone user for several years. Recently, the iPhone user upgraded to an iPhone 14 and now I no longer receive his group texts. He and I can exchange texts with each other just fine, and he can receive the texts I send in our group but I don't receive his group texts. We've checked the Message settings on both phones and they appear to be correct, and we are both up to date with the latest iOS version. I am on BoostMobile and he is on Sprint. I'm sure any attempt to explain this to a BoostMobile support tech (assuming I can get a hold of one) would be an exercise in futility, so I'm turning to the Apple community to see if anyone else has experienced this type of issue.

Whomever can't receive the MMS will need to trouble shoot with their phone carrier as it is their feature not Apples, only they can resolve the issue.
