The edge of the bamboo tray has come away from the cover during shipping. I can see the glue, what do I do?

We use a pressure sensitive contact adhesive to attach the bamboo tray to the cover and sometimes it may separate during shipping if there wasnt enough pressure applied during assembly.  Our assembly team can get tired at the end of a long day of building.   The very simple fix is to put the DODOcase flat on a table and apply even pressure all around the bamboo tray by pressing down with an open palm.  This will activate the pressure sensitive adhesive and the tray will be firmly attached to the book cover.
