I'm using tap talk...My PC is 2370 miles away....I'm 20 miles east of Nashville. I can access PM's sent OK, and the 1 I had I deleted but don't know with this format how to see and delete the ones I've sent.
If you use or download the FRF app you can , go to your messages / inbox or sent /press and hold the message (prompt)you can forward or delete. Could give that a try..
Sorry I dont use the "Taptalk app "
Or maybe someone who uses taptalk will chime in
