Issue Details

• AdGuard version:
  • AdGuard for iOS 4.5.2(1010)
• Device model and storage size:
  • iPad Air 4 256GB
• Operating system and version:
  • iPadOS 16.6
• Browser or App:
  • Safari

Expected Behavior

I am trying two filters I know to work on desktop, and have checked the HTML with Web Inspector, to block suggested posts on Facebook.

Both of these aim to do the same thing:

facebook.com#?#:xpath("//div[@aria-posinset and .//h4//*[@role='button' and .='Follow']]") facebook.com#?#[aria-posinset]:has(h4 [role=button]:contains(/^Follow$/))

But the post is not blocked.

Actual Behavior

The post should be removed, like what happens on desktop (uBlock Origin for Firefox).

Screenshots

View screenshots to see it working on desktop and not iOS.

Screenshot:

### `:xpath` rule on desktop  ### `:contains` rule on desktop  ### Both rules on iOS  (The third rule not circled funnily enough does work, even without `#?#`.)

Additional Information

I have force closed and reopened, toggled off and on multiple times. I have seen rules finding elements contained in that post work without using extended CSS selectors (a basic ##h4 [role=button] rule for example). I have tried simpler rules for :contains (like ##span:contains(Like)) which also don't work. I have not yet tested this on another site. I also tested the rules on iPhone 13 iOS 17.0 to no avail.

Elements may be named differently on a desktop and a mobile device. Please try to Open AdGuard action extension (go to Safari -> tap on Extensions button in the URL bar -> tap on AdGuard), then tap on "Block elements on this page" and choose an element. So the rule will be added.

@ESurina I am using show desktop view and I have verified via Web Inspector extension for Safari that the HTML is the same and it should be caught here.
