I customised the header and inserted on a page, but when I hit preview, it disappears.
And I just don’t know what I’m doing wrong.
Could someone please help me out on this?
Thank you so much in advance.
In my side, the header show correctly. Try with Chrome, Safari, Firefox, still same result? And now, when you share your app, you can Activate Read Only (view only). So no one can change your code by accident 
Thanks alot.
I’m using chrome but it just disappears as soon as it’s loaded.
Hey~ Sorry to ask another novice question,
but where is the Activate Read Only?? option?
Thanks for your kind help in advance.
Hi! Did you ever solve your problem? I’m experiencing the same thing, I created a header but when i go to preview it’s not there.
I wish they would bring the “add stripe” button back… 
Hi! I’m having this same problem with my app now. Any ideas on how to fix it?
