Hello,
I have detected some issues related to the Opera Synchronization when you decide to make an account with them:
1 - It doesn't seem to suggest passwords unlike you are generating yourself passwords each time after you make an account with them
2 - Peer to a mobile phone is sometimes harder and works after so many attempts so not from the first time
3 - The website doesn't seem to work perfectly with TimeWall, so sometimes Submit for job form doesn't work after so many clicks or even the form is incomplete or could not upload an image or empty text or the timer doesn't work
4 - There is a mute tab but you need to go manually to sounds each time a website is generating sounds to disable it forever
5 - The website needs to clear data if the website is gender redirected to another page like aviso bz, SEO time, Clix wall
6 - Listening to music on Spotify has several issues under Opera Browser
It is good to alternate working with another browser in parallel as some functionalities doesn't seems to work perfectly unless you are running another browser like brave browser.
