As admin, I cannot use the debugger to test if SDK is working. The full permission has been set for the property. The property was created/approved recently. Never worked before.
Reproduce:
In [Monetization Manager -> Issues] I can see this We haven't received a bid request Check the SDK integration is correct or use the debugger tool to identify any potential issues and fixes. [Go to Debugger Tool] is linked to the debugger tool page. Click it and it shows just like the picture attached.
Thanks in advance.
