Messaging App attachments not working

[Joey Golumpus]

I'm on Android 9.0. In the main page, messages say "New message available fo..." and when I tap "Tap to download" It just spins and spins and never downloads. I'm almost sure I've tried everything I could find on the internet about fixing this issue. Any idea why this doesn't work? Sending a picture message to myself doesn't work either, gets stuck on "Sending...". Regular messages seem to work fine.
I made sure my APN settings are correct (I had to manually input everything to get my service working). I've tried clearing cache for the app. Tried fooling around with app settings regarding downloading attachments. I'm out of ideas.
Thanks!

Solved: I made a typo when manually inputting APN Settings. I mistakenly put a space between commas in the APN Type field
Note: Don't do this, it will cause the whole thing not to work!
