How to get rid of ads on the start page on mobile browser

Description of the issue:
From time to time I get ads for some coin-related stuff on the start page, although I deactivated all advertising.

How can this issue be reproduced?

  1. Create a start page
  2. Have a look at the ad, if one is displayed

Expected result:
I expect the start page to be clean, ie it should show the background image and the widgets, that I selected to be shown on the start page.

Brave Version( check About Brave):
Most recent version for Android

Mobile Device details
BlackBerry KEY2

Additional Information:
As it has been stated in other posts already: Some of us are here to earn coins, others are just looking for a fast browser that respects privacy and offers security. I would love to have one switch saying “Do you want coins” - and if that option is disabled all Brave rewards, coins, BAT, ads and everything else should be hidden. This setting should also be synchronized between all devices.
