Group messages on a S20

[user4w4ekpcBdO]

everytime I send a group message out or reply to a group message, my text don't go to the group as a whole, but everyone gets seperate messages from me.  I already have the setting set-up to be group messages, but it seems to not work.  Not sure if it matters, but i am using the default messaging app that was already on the phone.

my group texts were fine on my note 20. it just stopped working all of a sudden.

The group messaging works fine in the Google messaging app, but the native Samsung app is having trouble.

it also won't let me select "group conversation". i select it, but it doesn't stay selected. Note 20 Ultra
