When you say you are using Admob and it's causing the errors, you mean the "MobileAdvert" plugin?
...because I'm using it on iOS and Android and it's working.
If it's not this plugin, what is the use of "AdMob" in a game...?
I still have some headaches with some plugins too, hoping Construct 3 dev team will look at my bug report from 19 days ago... :/ I still trust them...
...but I have to admit I'm looking forward to have more fun working on my game, than going trials and errors to understand wich plugin is causing errors sometimes.
