When trying to spin the wheel or to get the bonus for the next 4h, I currently receive the message:
"Sorry, no ad was available. Please try again later."
I am running the most recent apps Warzone and WZ Idle both Version 5.36.0.3
I tried WLAN at home, mobile data and different VPNs, with every connection type the same result.

In the past I had this message sometimes from WLAN, changing the connection to mobile fixed that problem.

I also rebooted my tablet, situation has not changed.

Any ideas?

Had the same issue last year.

Resolved itself after 3-4 months.

No idea what caused it, I filed a ticket on it.

Resolved now after 5 hours. Looks like, that a google ad server was not available.
