I'm having to wait approximately 15 minutes each iOS build. This has been happening over the past few months.
I'm using public release version 2017.3068 (2017.3.31)
The only difference from my other games is that I've added the Appodeal plugin. The generated file size (.app) file is about 45 Mb. I wouldn't have thought adding the Appodeal plugin would be the cause for the delay in generating the build.
I was able to generate a build in about 2 minutes a few months ago.
Any help would be greatly appreciated. Maybe it's time for offline builds?
