I added the widget to my sidebar and it works initially, but after refreshing the page it sometimes disappears. I tried clearing cache and re-saving settings, but the issue still happens. Could this be related to the theme or customizer? Any suggestions on how to debug this?
Thanks for posting your question. Do any of your plugins add lazy loading or image optimization of some sort? You could perhaps check to see if the issue persists with only SiteOrigin plugins activated?
