Hello,
it’s been several days since I can not pack my project because of a problem with gradle. I do not really understand where it comes from since I have always been able to pack this project …
The ads in my game did not work well and that’s why I decided to buy a mobile ad pack (super expensive in addition- $ 120) and since then I have errors or gradual according to if I check Gradle or not.
I have already covered the topics on the internet and the EU forum but nothing works. I hope you have a solution to my problem! Thanks a lot
