Hi, I'm working on mobile app and I have two problems that neither Google nor the manual helped me: 1) First is probably trivial, it's about Admob and mobile debug output. I need a deviceID for a function GoogleMobileAds_UseTestAds(use_test_ads, deviceID), but this variable is (by Google Mobile Ads Manual) from "debug output". It's probably simple show_debug_message output, but I can't see anything. I tried the classic show_debug_message("test"), but it did not show me anything when I was testing on my mobile phone (via cable). Is this normal behavior? How do I view the debug output on Android and not only in Windows 10? Breakpoints works fine during debugging, but output not. 2) It's about IAP. I have followed this manual: https://help.yoyogames.com/hc/en-us/articles/360031457831-Android-Google-Play-Billing-IAPs- . I probably miss the last step to success. The big problem came when I tested implementation of purchasing a product. I didn't get any asynchronous response from Google API. so the switch branch named "case gpb_iap_receipt" was not performed at all. Anyone please know what to do? These are probably the last two things before my application was released.
