This was new listings on the old page, I saved them as drafts and couldn't preview from there either. As preview isn't available yet on the new listing page (which I loathe) there's no way to preview at all, is it just me? I'm using Chrome on laptop and not the app.
Okay, it's not just me then! I'm having the same problem. I'm using Edge on my laptop. And I'm using the old listing page, not new.
Not just you-it is still happening to me as well (using old form because new form STILL does not have preview anyway) and I'm using Safari on my MacBook.
Aha! not just me.
