I had the same problem. After buying the new Samsung S10+, I thought it was the phone. Then I did the search online like everyone. The I realize what it was.
Note, I did NOT have these issues on the new Samsung 5Se Tablet or my Acer computer at home. On my home computer I have ADGUARD, MALEWAREBYTES and Kasperky Total Security, now Bit Defender Total Security. On my tablet the same minus Adguard. On my phone, the same as my computer.
I am NOT sure this will help everyone....but after going BONKERS checking every security and nook and cranny....I realize when I opened up Adguard on my computer and phone SIDE BY SIDE....and went down all the settings....to make sure all the check marks matched....only one did not....and that was on the computer.
On my computer...I did NOT set the HOME Parental Thingy.
01: Go to Adguard, then Settings
02: DNS Filtering
03: Select DNS Server
******04: 4 whatever reason, I chose to NOT use Stem default. I chose to use AdGUard DNS Family Protection. When you see this, it says....adult content blocking. When I fiddled back and fourth with this one and the REGULAR DNS....and went back and fourth numero uno times on youtube.....I REALIZED....in AdGUARD....EITHER USE SYSTEM DEFAULT, REGULAR ADGUARD DNS ....BUT ANYTHING BESIDES anything WITHOUT THE {FAMILY} listed.
IT WORKED FOR ME......YIPEE!!! =0P =0P =0P And it took me over 72 hrs. to figure this out....SHEESH!!!!
GOOD LUCK EVERYONE.....HOPE THIS HELPS. PLEASE SHARE W/OTHERS AS I AM SHARING W/YOU. THANKS!!!
