I have noticed that after upgrading from previous Opera to the new One version instagram has been logging out by itself. I don't know if it's a problem with the browser or with Instagram itself, but I can say that in other browsers, Instagram is not logging out on its own.

After the last update of Opera for Windows, the My Flow feature disconnects from the account by itself and every time I have to scan the QR code on my cell phone to access this feature.
