@Timespansoul said in No MMS with Wifi ON:
Could you verify that it also works via Messaging app?
MessagingApp is basically just an app that reads/writes to a sqlite db. Everything about MMS (checking, downloading, storing into db) is done in background and is handled by more processes. So your question about Messaging app is kind of irrelevant. And yes, I used the Messaging app to see if the MMS message was successfully delivered.
I've already did some research and written somewhere about this already. If I recall correctly, I didn't find the cause, but narrowed it down to some package. Try to search this forum and/or gitlab/github.
