Guy at home depot told us 20 years ago their vinyl plank flooring interlocked with adhesive and could be placed right on concrete. Was he wrong. Looked like he double hockey sticks in under 10 year with adhesive edges letting go & any rough area or crack wearing through the vinyl except on the plywood raised portion of washroom. Pulled vinyl, sounds like same labor intensity you are experiencing. Did some research to avoid plywood sub floor and settled on 2 x 2 foot squares of interlocking plastic which actually has 3/8 area beneath to allow floor to breath and condensation escape. Dribarrier is not cheap at $3600 for 1800 sq feet but i will never have go do anything else to it. Wont help you pull up but avoid installing it.
