So, i prepared email template as per my preference, no issues, happy with it.

Now, when I sent out emails it has errors on the mobile display, but okay on the desktop. Is this common for klaviyo, that I have to make the template twice for mobile and for desktop? On mobile it just says “Headline” and some basic images provided by klaviyo all wrong.

Thanks

Hi ​@eddio,

Welcome to the Klaviyo community! By any chance, does your email template have mobile-only blocks? You can check this by going to the template editor and switching from Desktop to Mobile, in the bar at the top of the editor. After that, mouse over the blocks and sections in your template. Do any of them have a little phone icon next to them? If so, that means that these blocks are only going to be shown to people viewing on mobile devices. You can edit/remove these blocks if you’d like.

If that’s not happening, would you mind sending over a screenshot of how the email looks in both desktop and mobile view? That’ll help me determine why this may be happening.

Hi.
Its one of the templates I randomly selected from the library.
Well, when I switch between desktop/mobile views some blocks have small mobile and a small desktop icon at the top left, depending from which viewport I am viewing them.
What’s the idea and workflow adding such “feature” as it is complete opposite of what it normally would mean in any other editors. What I edit/add on desktop automatically transfers to mobile view and If I dont have an extreme design, I shall not need to check on the Mobile as I would expect everything to be reflected on the mobile.
Feels very wrong this editor. I do understand, the feature of having some data to be shown only for desktop/mobile views, but that should have a separate trigger - Responsive selection mode or whatever, where I manually select which blocks will get shown on desired viewport. 
So, why by default I have to build the template twice?

Thanks
