Webviewer loading problem


I got a webview that shows shows a web page, and it doesn’t work on all devices.
It just show a blank screen on those it dosen’t work on.
I have tested it on 2 of the same mode ltablet even and one it works on and the other it does not.
Any one have had a problem with this before and can come with some tips to fix it?


Do they have the same OS on them?


Yes, both of the run android 6.0 and has both gotten the same updates.


I was hoping someone else would have a suggestion for you.
I have not experienced this particular issue before.

I assume that the same website opens correctly in Chrome or a different Browser on this device?
