Any way to make multi-property ribbon look better on mobile phones for cleaners?

Here is what the multi-prop widget looks like on my phone:

Is there a way to make it more usable?

Yes, the widget is designed to automatically resize smaller on phones. However, looks like your site layout is actually doing the opposite and zooming farther in on mobile, making the text bigger but keeping it from laying out correctly.

It also has quite a bit of whitespace on the sides -- looks like about 20% of the horizontal space is taken up by whitespace.

Remove that extra whitespace and the zooming and that should solve the issue. Looks like you're on WiX so you'll need to tweak the separate mobile layout. Check out steps 8-9 here: https://www.ownerrez.com/support/articles/wix-widgets

Here's an example of what the widget should look like on mobile (this is on an iPhone 5, so quite a small screen):

and remember to tell your team to turn the phone to landscape. On mine it switches to showing a full month so much easier to read.
