I opened this topic about package import errors. So as i see, nothing has changed after that. Because i use 2019.3.0b5 or b7 sometimes and i saw alert about it again. So i gave it try. Still lots of errors while importing. So i’m gonna download 2018.4 again, import it in there, then copy files to my project. Thanks for doing nothing about new versions and sticking to old versions.
Sorry I don’t follow, perhaps provide screenshots and specific steps to reproduce. Are you referring to IAP import?
I managed to solve it. But i don’t remember how i did it. I think i copied folders from older version again. Or installed udp from package manager then installed iap and bypassed udp installation.
