In at least 90% of the occurrences, it is a room temp tank or rda off the shelf.
Creating atomizer profiles wouldn't work for me, and should not be necessary. I have too many duplicate rdas that get interchanged throughout the day to change flavors. That would be a bookkeeping nightmare.
I am willing to try new things but atomizer profiles seems an unnecessary burden when this appears to be DNA250c problem.
And, just for the record, I have also submitted a support ticket.
If you do a search here on "Temp Protect" you will find other similar behavior has been encountered, although perhaps not as well documented. I only because concerned this was a DNA250c problem upon buying my second device and having exhibit the identical behavior.
All that said, thanks for the reply. It never hurts to pursue different avenues of resolve.
