Thank you for your answer, but alas, these devices are not in the browser, nor in the browser settings, but only on the Opera account website...
Besides, it is easy to delete the "other" devices in the browser's favorites and "Speed Dials" but it does not influence the Opera account website.
Nothing is present on the Opera account website to erase these devices.
t's crazy that for so many years, nothing has been planned for this!
Guess it only bothers me !!
Why the developer does not add a checkbox on the right to be able to delete the devices that we want ?
Having to do a reset for delete everything is an aberration !!
