Unable to download MMS and recieving random ones

[AC Question]

My galaxy s6 is semi new, and I was addes to a group chat with some people I know, but was never able to send messages in it for some reason. I recieved some error about MMS. Anyway, now ive also started recieving random 1kb undownloadable mms from people in the group, and my phon has a small popup in the bottom saying it failed to retrieve mms message.
