Filamentum Flexfill TPE96A bed adhesion

I have been using this stuff for a few weeks and had some good results using both the Filamentum Flex 98A and Semiflex profiles.  It took me awhile to get a decent print because it didn't seem to want to adhere to the build plate.  Anyway, I redid the first layer cals and cleaned the plates.  Interesting that the Prusa table says to use glue stick with smooth or satin plates which makes for even less adhesion.  I could never get any adhesion at all on satin with or without glue, but did a fair number of good prints on the bare smooth plate.  Then all of a sudden trying to print the same exact model that I just pulled off the plate and I get the spaghetti monster.  And again.  And again.  It loses adhesion and lifts off the plate.  I redo the first layer cal, clean the plates and no joy.  It just won't stick.  Same exact model, same build sheet.  I even relocated the model to a different position on the plate.  Just will not stick.  What the heck is going on and what can I do??
