Had my P1S for 4 months now. Never had to use any glue on Textured PEI for PETG, PLA, PLA+ or TPU although TPU sticks so good I have to lay painters tape down then it comes off like PLA.
The trick for TPU is to remove it while the plate is still hot. PLA/PETG ideally you want to let the plate cool to room temp at which point the prints will basically self release. TPU sticks harder to the build plate as it cools.
When fresh from printing it does not come off and I nearly tore my fingernails off in the process. With tape I can get perfect prints and ease of removal.
Just put a little watered down IPA on the bed where the print is and it’ll wick under the print and help release it.
