Hi guys! I have some problems with the Admob's reward ads (and sometimes with video interstitials as well). The ads look normal with the exception of screen controls are missing. There is no any timer at the top and the close button (x) is missing at the as well, but in most cases there is a black screen and there is no any way to close an ad at the end. The only way is to suspend the app and then to return to it, after that all controls including the close button and so on magicly appear and the ad looks like it should.
I'm currently using the build 3549, but the issue exists at least since summer. I'm testing it on Google Pixel, but rewards don't work on other devices too.
Moreover sometimes the bug occured when an interstitial is showing. The image is the same: screen controls are missing, there is no any buttons to close the ad, only black bars at the top and bottom parts of the screen.
In the logcat there is no any huge crash reports, only small errors like: 'E/Ads JS: uncaught TypeError: Cannot read property 've' of null' or 'E/SurfaceFlinger.... rejecting buffer'. And something about chromium. It looks like there are some problems with the webwindow for the ads or something. And all controls appear once you exit-enter the app.
There is no any issues on iOS, only on Android.
Thank you in advance.
