I have a LG V60 ThinQ 5G UW. A month or two ago, I started having an issue with sending MMS messages while on my home wifi. I can send individual texts fine, and have don't have this issue at any other time. I went into the a verizon store, they said "maybe it's the SIM card" so we switched it out. Nope, same issue. Does anyone have any idea what the issue may be?
