I recently tried out a new app on a clients store and it caused a conflict with the cart page and prevented a few customers from checking out before I realized what was happening.
In other website systems (Wordpress, Webflow, etc), I can make a change on a staging site, test it, then push it to production when it's ready. However, there is no staging site functionality in Shopify.
I know that if I make changes to a theme, I can test it on an unpublished theme. But this doesn't apply to apps, of course.
The only method I've found is to use the Rewind Staging app which is $99/month - far too expensive for my situation. Am I missing a way to test apps to see if they cause any issues?
