just a note, if you decide to use pressure to finish up the job (as opposed to waiting another month for the lens to just fall off), I would consider what others have said, the glass will crack if too much is applied. You dont need to see any movement when inserting spacers (chop sticks in my case) just snug them in to a void (which will be easy to make as you can pick out around the perimeter the softened pva). I gently tapped them into the voil until it sounded "solid" then walk away for a few min, observe the fingers starting to form, go around the perimeter again and tap to make sure still snug, walk away, repeat. It starts slow but the last 25% of the contact area goes very quickly, with a satisifing "pop" as it finishes up.
In my case it was a very sunny day, maybe 85, the glass was quite hot, I should have used my IR gun to check it but a ruff estimate would be 120f
