Tweetdeck cannot switch to light mode

Describe the bug
On iMac in Firefox my Tweetdeck picks dark mode as default (This started happening about 2 days ago). I have to go to the settings to change to light mode each time I reconnect to Tweetdeck (several times a day). As of today, april 9 2021, the toggle for light or dark mode has completely vanished, see screenshot.

The switch has not "vanished", I added the link for users to click and change the theme in Better TweetDeck's settings in order to prevent a situation where Better TweetDeck and TweetDeck have different opinions on what theme to apply.

Fixed in 4.0.3
