@xirit32 Yes, I did do that to open tumblr dashboard or to reblog post. But it makes me couldn't open dashboard everytime like I was using extreme mode. Also GIF post will automatically loaded and it used many data more than using extreme mode.

@dsplykan I've sent this report to opera on 14th july, and yet I still have not receive any reply.

@dsplykan Yeah me too… Opera mini is my solution for my poor internet connection and based by quota which I tried to saving my data.
It seems extreme mode has a problem for some site.
I've already sent email to Tumblr support and they said they were unable to support this browser.

I can't login tumblr on opera mini when extreme data saving mode is on and it always said: "There was a problem logging in, try again later".
I tried with my friends phone and opera mini to login tumblr, and there was no different.

But when I turn off the extreme data saving mode, I can login.

I just want to access tumblr with less data usage. That's why I use opera mini.
