Last night (9 December) suddenly started blocking all my Google Drive Docs. This has never happened before. I confirmed it was Web Protect by both going via a VPN and switching the service off and on again. It is definitely the web protect and not the parental controls filters.
We started having exactly the same issue on Monday and been struggling for a fix.
Any help appreciated
If you're having problems accessing your Google Drive please try disabling web protect and parental controls from extras section of MyBT. Once disabled login to Google Drive then activate parental controls again and it should continue to allow access when they are enabled. Post back and let me know if this helps.
