Hey there everyone
I'm using HeyZap with Chartboost mediation. SDKs are implemented correctly and are in green condition in MediationTestSuite portal run on android device. The problem I'm facing is the error massage NETWORK_ERROR: NETWORK_FAILURE when trying to fetch ads from chartboost
and NO connection or no fill when fetching ads from HeyZap
To insure it's not a device related problem I tested the app on multiple devices and various networks but still no response.
Here's a screenshot from the mentioned problem:
