No texts from Android phones

As of a couple days ago, my iPhone quit receiving texts from anyone with an Android phone. I can send them texts, and they receive it, but I do not receive a reply. All of the SMS, MMS, iMessages and Group toggles are all on. I can’t figure out what changed in the last two days, but the fact that it is more than one I am not receiving texts from makes me think it is on my end.
