I keep encountering this as well and I'm shocked to realize that this can't be removed forever or that it's even part of Opera in the first place.
For a browser that offers a built-in VPN and Ad Blocker and seems to care about privacy to slap something like this on a user's face is ironic and ridiculous.
I'm considering changing back to Firefox until this is removed.
@voyager2golf Well if this is not a want for click or refers, the page has loaded normally on my newly updated opera for mobile on my Android 7 with zero flaws. I surgest u enable all permission for the browser in settings and don't forget to clear your recent launch apps to gain enough RAM, disable auto cleaning apps like Phone Master, RAM booster etc if available and try again. Please don't forget to attached a screenshot
I found this solution on desktop https://youtu.be/goMrvrcBh90. There must be a similar way on mobile, I just need to access the right files or know how they are called there..
Eventually anyway you will have to organize bookmarks at that large amounts with Opera desktop version. The first thing to do is back up that many bookmarks especially the quick dials which are bound to a specific new installation. With desktop opera syncing, then export all to a .html backup. Then clicking folders selecting sort alphabetically, also doubles after alphabetically sorting show next each other and can easily be sorted out. Make sure before this many bookmarks sorting with desktop version of Opera to have the backup. It's best to do this once a year or so.
