Hi again, May have got round the problem instead of using and opening WhatsApp from the sidebar I opened it from a saved bookmark, and up to now no more problems.

Hi, Can't see the padlock badge in Opera's WhatsApp.

@leocg No not at the moment, tried several combinations with the same outcome.

No just WhatsApp.

Every time I shut down the PC or run CCleaner, WhatsApp Notification "Link Device" is required.
Dose anyone know which "cookies" or files should be kept and not deleted to stop having to "Link Device" every time?
