Buildbox 3 beta 2 crashes immediately as i add ads through mopub can anyone help in this regard thanks..
Of course it is. Still Beta. Sometimes it crashes on Previewer when playing with the different device resolution. Still less crashes with respect to RC1.
Remove the ads, save it as 'ads free version' then build it, to see if it crashes. Otherwise it's just a needle in a haystack to figure out a solution. If you remove the ads, the problem will be there.
