I need to tell you about something that happened a few weeks ago.

The reality: you only find out when revenue drops. The app overwrote and it blanked the screen.

The Discovery

Eventually I cleared the cache and everything worked again. The reality: you only find out when revenue drops. What I cannot get over is the platform should catch this. What I learned: testing your own store is the only safety net.

I review weekly. What I cannot get over is nobody tells you this.

The setting disappeared and it blanked the screen. The store froze and it blocked checkout. What bothers me is there was no warning.

The Aftermath

I spent all night trying to figure out what was happening. I test before any launch. Here is the thing: most merchants do not know this happens.

Turns out the theme file was corrupted. What I learned: most merchants do not know this happens. Here is the thing: testing your own store is the only safety net.
