Digistruct Peak Overpower

Played on UVHM On Digistruct Peak played solo and completed, turned in to Tannis, exit and save, played same again completed again still no OP, it did say play again and OP would happen but no joy?

You need to be level 72 and do it in UVHM. You should be getting a message saying that you’ve completed a run, After turning it in, just save and quit. When you select continue you will get the option to select your OP level. You will always need to save and quit in order to change OP level.
