Oh my dear Groundspeak, it seems you are not living in actual time. Yes, I can confirm that Opera Mobile Classic works now on GC.com with activated "Opera Turbo". But it doesn't work well. The loadingtime is longer than without Turbo Mode and the site will not be loaded completely. Opera Mini and Opera Browser in Offroad Mode still doesn't work on GC.com.
Dear Groundspeak,
thank you for activating the access via Opera Mobile Classic in Turbo Mode. But Opera Classic is the dead horse of the Opera Browsers. Mobile Classic will no longer been maintained and updated by Opera. The actual Browsers are "Opera Mini" and "Opera Browser" (with Offroad Mode). The community will thank you very very much, if you bring us back the access via these two browsers, specially Opera Mini.
Best regards
Gerald
