Screen very difficult to remove

Amazon Fire HD 10 screen is EXTREMELY hard to remove. Using the correct plastic tools from ifixit, I carefully started near the upper right corner (next to the power on button) and worked the side of the screen loose. At the corners, top and bottom, I could NOT persuade the outer case to part from the screen/digitizer section. After over 2 hours trying I am hoping that someone has a better way. Maybe the glue formula has changed? I do have solvent used to release the Apple MacBook adhesive. Any info would be appreciated.
