Unity ADS on Android device Not Loading Rewarded Video

Hello everybody
Added Unity Adsense to the project, and everything worked well on the android device and in the editor.
I did not change anything in the code and settings.
But Now advertising in the editor works and on the device does not.
Tried all methods specified on the forum, change settings on the desktop, initialize, create a new project, internet connection is fine BUT no results.

On the device.
Advertisement.isInitialized gives a positive result - so the initialization has passed
Advertisement.IsReady ("rewardedVideo") - does not give a result, so the video for some reason does not load, even the test

Цhat could be the problem?
Any advice?

 

As same as my Problem Here

 

It's a pity, the same story you have
I made a new clean project for a test with one click of the ad call, but so far the result is still no.
The only thing that comes to mind is to test it on another device. Or build on another computer

 

Well. I've two Android Devices with different Google Accounts here for testing.
One Samsung Galaxy S6 (My "Default Phone") and one Samsung Galaxy A3.
mysteriously the A3 can show ads

 

I had an idea that the problem is in the security settings of the phone, but so far there is no result

 

I've compared my Phones. Here are the differences besides the version.
Both are connected to the same WiFi connection.
Both Phones are using the same APK.
The Galaxy S6 stucks after Initializing UnityAds. Advertisement.isReady does not return true;
Maybe the root causes that problem.
Is your Phone rooted to ?

I can test it with an other Phone from a friend.
His Phone is not rooted.

EDIT : He just installed my App. Ads are working on his Phone

Code (CSharp):

1. Phone                                 :    Galaxy S6 (SMG920F)        Galaxy A3(SM-A300FU)
2. Ad working                            :    No                         Yes
3. Rooted                                :    Yes                        No
4. Android Version                       :    6.0.1                      6.0.1
5. Apps in Background                    :    None                       None
6. Google Account(s)                     :    (1)                        (2) & (3)
7. -Remove Personalized advertising      :    Disabled                   Disabled
8. Dev Options                           :    Enabled                    Enabled
9. -USB Debug                            :    Enabled                    Disabled
10. -Mock Location                        :    None                       None

You can test it yourself

 

I am so stupid ...
Just found the solution.
The root is not the Probjem. its the Ad Blocker. He does what he was made for...

You can view my Working code in my thread

 

I tried to reset the phone to factory settings, I did not install any blockers, but it does not load the video,
Did you solve the problem on your phone after off the blocker?
Maybe there are some settings in the phone that I do not know about

 

Yeah. Advertisement worked after disabeling and restarting Phone.

 

I am glad that it turned out.
In my case, restarting the phone did not help.
But on the phone of a friend advertising works
That only confirms that with the code all is ok the issue is only with the phone.
It remains to protect the user from such a case

 

Do you may have Pi-Hole installed on your Network ?

 

There is nothing specifically done with the network
The funniest thing is that advertising worked before on this device
So the idea that problem only with device. with its settings but where
and how to protect user from such problems
