For mobile devices, the timeline bar will display as an oval for some events but as circle for others. This isn’t an issue for desktop devices. I would like the progress bar to display as circles across all events. Here is an example:
Hi there, @andrewchin 
I am so sorry about this issue!
I’ve passed it on to the devs and will update you once it’s fixed 
Thank you Max, I really appreciate it!
Hi there, @andrewchin
This issue appeared because of the .global-styles, element used in the CSS code of your Popup widget. I’ve removed .global-styles, and the markers are displayed correctly now.
Please check it out and let me know if it’s fine on your end now
Beautiful! Everything looks great on my side. Also, now images are consistently the same size which is amazing. Thank you again Max!
It’s my pleasure
