Ads are not showing for projects made in BB 2.2.1. If I open them with 2.0 and export to iOS the ads show. So the ads are set up correctly. Seeing this problem with Charboost and Applovin.
In the version created with BB 2.2.1, it has this in the xml file: <dict> <key>selectedStringValue</key> <string>kChartboost</string> </dict> <key>Ad Banner</key> <dict> <key>selectedStringValue</key> <string>kNoAds</string> </dict> <key>Ad Interstitials Freq.</key> <dict> <key>value</key> <string>2.000000</string> <key>animations</key> <array/> </dict> <key>Ad Banner Freq.</key> <dict> <key>animations</key> <array/> </dict> If I export from older BB, it has this: <key>Ad Interstitials Freq.</key> <dict> <key>value</key> <string>2.000000</string> <key>variableValue</key> <string>0.000000</string> <key>useDefault</key> <string>1</string> <key>isEmpty</key> <string>0</string> <key>useDefaultVarible</key> <string>1</string> </dict> <key>Ad Banner Freq.</key> <dict> <key>value</key> <string>1.000000</string> <key>variableValue</key> <string>0.000000</string> <key>useDefault</key> <string>1</string> <key>isEmpty</key> <string>0</string> <key>useDefaultVarible</key> <string>1</string> </dict>
