I noticed when accessing panel it’s still not forcing ssl even if the option is enabled for the site. Since I noticed when accessing panel via http but frontend via https, it’ll log me out, so I’d like to suggest to enforce ssl on panel too.
Sounds good. I have added a feature request issue on GitHub. 
Just opened a PR that approaches this issue: https://github.com/getkirby/panel/pull/801
Got added to the develop branch, will be included in the next release.
