Hi there, I'm developing my first ever project alone and I tried to add Unity IAP, which opened an IAP installer with prompts to import 2 packages. First package was completed, and I started importing second one, when it got stuck at Facebook file. It just adds new iterations to that dialog window. 1 iteration per minute or so. I tried restarting Unity, but the dialog pops up even before project opening and continues that infinite loop. Please assist in troubleshooting. Can I just delete some folder in project to fix that? Thank you!
