ChatGPT led me to this comment, as I was searching for issues like mine.
I use Firefox browser, and no matter what I do, the reading pane is squeezed to about 1% of the screen size.
When I grab the reading pane (on the right for me) and drag it to the left, the From: Date: and other columns become less than 1% width, i.e., unreadable and must be manually resized, each one of them every time I log in.
I find this happens on Google Chrome browser also, but not as often as with Firefox. Even in private (zero addons in use) this issue is persistent.
This issue has been present for almost 6 to 8 months. It's only now I decided to look on the Internet to see if it's "me" or something in Grommunio that is causing this.
