Some texts not coming through

Recently I have been receiving texts hours later, receiving them out of order, and possibly not receiving some at all. Does anyone know how to resolve this?

I noticed it when texts in a group chat didn’t make sense and realized that I either am missing some completely or they came out of order. Some texts (with and without pictures) came through hours after they were sent today and yesterday.

iPhone 15 pro. I believe these are only regular texts, not iMessage.
