All is Ok except the online video streaming feature, which is played by Opera Mini's built in media player. It’s very much annoying to wait for a long time because if I tried to play/stream any video Opera Mini takes hell lot of times to load that video. Moreover, if I rewind forward & backward, ah it takes more time to load & play.

Why I've to login everytime in Gmail (https://mail.google.com) everytime after restart Opera Mini, though I was logged in & I didn't do log out.
Opera Mini logged me out from Gmail automatically after every restart. WTF !!!!!
Fix this Please.
Using Opera Mini 38.1.2254.136033 on Android 6.0
I use both 3G & Wifi network.
I've installed "Android System Webview 72.0.3626.105 version"

From Opera Mini 22 or 23 version to latest 38 version it's the same old shit. Nothing new, no bug fixing, no nothing.
Still facing many problems from those previous version. It's like a kind of dead browser. Every new update changelog says nothing but "Various stability & usability improvements"
The same old thing as previous

*- Online Steaming Feature

Using the latest version.
Everytime I restart Opera Mini everytime it does automatically logged me out from gmail. Everytime..
And Online Feature is too poor to use.
Fix problems & make some improvement.

Crappy ads from Opera itself.
This browser block ads to make your browsing experience better but it shows ads inside that makes your browsing experience worst. Kind of double standards they are following.
By the way, Opera devs doesn’t pay attention now a days.

Online Streaming feature Sucks.
It takes too much time to load any web video for streaming. And if I do rewind then sometimes that following video totally stops to streaming & sometimes takes even more times to play. Totally Annoying.
And while audio streaming, there has no way to rewind forward or backward play.
Everything Sucks.

I'm facing same problem.
I tried to sync my Speed Dials & Bookmarks by signing in my Opera Account from Opera Mini's setting. After logging in I go to https://sync.opera.com and saw that nothing was synced at all. While I have more than 10 Speed Dials, 5 Bookmarks on my device but at the Opera Sync service I found nothing.
Currently using; Opera Mini 37.4.2254.133967 on Android 6.1
Using both WiFi & 3G network connection and this problem remains whatever mode I'm on Opera Mini.
Please, fix this ASAP

Now a days I've got another problem. With Automatic & Extreme mode; In Facebook when I click anything, any profile or any button, I frequently got
"Sorry, something went wrong.
We are working on it and we'll get it fixed as soon as we can.
« Back to Home
Facebook 2018 · Help"

This happens when Opera Servers got updated to version 4.123 & still on 4.125.31 this problem still remains.

And I'm totally dissatisfied with Opera Mini's media streaming feature. It sucks miserably.

Still there has problems. Opera Mini takes too much time to load any video for video streaming and if I do rewind that following video it takes another hell lot of time.
And while play/stream audio file, we can not rewind the playback forward or backward.
In Extreme mode, Sometimes facebook images doesn't loaded. If I do refresh the page then those image will loaded. Sometimes File downloading speed got super slow & if the download got interrupted then most of the times resume doesn't work.
And the full screen ads. When I'm in the middle of an important work then Suddenly a annoying full screen ad just comes up & makes me crazy.
