I have been using Opera Max to save data in my Android phone since it was in Invite-Only mode using Google+, and always faithfully "refresh" once a week. I have realised that it hasn't been asking me to "refresh" for months. After I open the app, it gives me error message
"Could not connect. Check your connection and retry."
I wonder if this is common problem after recent updates?
It's weird replying to my own problem, but apparently after I reinstall the problem's solved.
