Hi, I'm a long time Opera user, since the 90s, but now when Chromium is used as the main engine I can see Opera uses sneaky ways to put advertisers on my custom SpeedDial screen, I've seen this from time to time, sometimes they put 4, sometimes 1 sponsored page. Do you see the same sneaky behaviour?
On Android, I got a "starter set" in Speed Dial, including:
Play Now
Free VPN
Amazon
CNN<p>then later, they snuck in:
Nordstrom
Walmart
Booking.com
