Same here, I get constant Street Signs (about 5 images) always fails
, Bus, Cars, Bicycles, Store fronts and Fire hydrants images that ALWAYS fade slow... and fail
In the event that is does "pass" so the website returns an error that "Captcha verification failed" or anything like this so I can't login or do anything.
For some reason it starts ok on the first 6-7 websites and after it it start to mess up, even if I log off from my Google account it continues, though for a week it worked ok, same goes if I do it on my mobile phone or tablet (And NOT connected to WiFi) so this can not be a network issue.
It does become "ok" after a few hours but, again, after 3-4 websites it goes wrong.
Now, I did:
Cleared cookie and web cache.
Rested Wifi (both router and card) though if my mobile devices fail on cellular network so I see no logic...
Malware scanned with 3 powerful apps (Malware bytes, Spybot and Panda dome) no results.
I do not use VPN (used in the past but uninstalled all of them) again if my mobile devices also fail so no logic...
I have no "bot" or scripts for whatever reason...
The only method that is "working" for now, is to use privet browsing, but this is not a solution...
So I do hope I get "unblocked" or get someone from Google Captcha team to see this because this is really making browsing and life hard.
