As others said, dish soap over IPA. I’ve also had shite PLA before as others mentioned. Find a good brand and stick with it. Also, magigoo is amazing. Basically glue but not glue. Designed to stick when the bed is hot then release when it cools. I add magigoo any time I have a long print where I worried about potential warping or lifting.
Same, minflux is simple and very lightweight. I just use a we app on my phone to read it. Still very responsive.
