I use Opera on PC for 10 years and on Android for 4 years. My passwords have always been well synchronized between PC and Android. For 2 weeks, I don't have any password on Android 7.0 anymore!
The sync settings are set correctly to synchronize the passwords. I disconnected and reconnected Opera Android and PC several times, without success.
Is this a known bug?
Thanks for your help!

I can confirm the issue when browsing in extreme data saving mode.
One can workaround it by replacing "www.reddit.com" with "old.reddit.com" in URL address but this problem needs a fix by Opera (f.e. through Opera Mini's browser.js implementation) or by Reddit (by redirecting Opera Mini extreme mode users to the "old" version of the website).
