After receiving 86.0.587.0, websites show the "Cookie reminder" after each Edge restart, sometimes even after simply returning to the top domain of a website.
Also, websites requiring a login lose the login information after a restart of EDGE, so that a fresh login is reqired.
I work with "don't save passwords" but with bitwarden. Has worked like a charm until the new release 86.0.587.0, login was carried over restarts, cookie reminder popup did not show all the time, only after deleting cookies manually.
Attached a snippet of a website continuously repeating the cookie alert message (avherald.com).
Pages losing login information are e.g. "tagesanzeiger.ch" or "blick.ch".
