The error message 'blocker of unwanted content not available. Please contact the developer for details.' displays when starting Sbrowser. I have a UK Vodafone S7. ABP for Samsung displays in the Sbrowser 'Block content' options and is turned on. Ads are currently being blocked so it appears not to be affecting functionality but is annoying all the same as it makes me uncertain that it is functioning.
It doesn't display when opening new tabs. If I am active in another app then go back to Sbrowser it doesn't occur. If i close sbrowser in recent apps then reopen the message recurs. I guess that switching back and forth at short intervals the process remains open and that the error is on starting the app. It sounds very similar to the defect #4041 that you declared fixed with v 1.0.3
Thanks for your attention.
