QuikSet tape no longer holds

Has anyone else had recent trouble with the Quikset tape not staying stuck? Until a few weeks ago I had no trouble with the Q-set staying on 3-4 days. OK, I know it should be changed after 3. But now the tape curls up around the edges within 24 hours and by day 3 it is almost entirely loose.
Note: Nothing has changed about my sites or prep.
I have always cleaned with IV Prep and I still do it the same way I always have. Lately I have even had to add strips of Flexifix around the tape edges which was previously unheard of.

Anyone?
