I have also noticed the bond is not what it used to be. Turning to gooey mush after only 10 days in the back, and the front lifting up after less than a week, in some instances. Maybe it's just a bad batch. Fingers crossed.
What would be nice, if there was a super tape that had red liner on one side, and their super adhesive on the other. One side sticks to the base and one side to the skin. Would cut re-taping times in half, and save putting two thicknesses of tape on the perimeter. Maybe it already exists, and i just don't know about it?
