I’m happy to hear it’s working for you using local storage!
For the purposes of other folks having the same issue and coming across this thread, I wanted to close the loop.
It doesn’t appear that the cookies are being set properly. When I view them on your site directly:
You can see that both the
SameSite columns are empty –
Secure should contain a checkmark, and
SameSite should contain the value
When viewing your page within the Market iframe, no cookies are loaded (since they’re missing both values). I built a small test webapp inside an iframe and can duplicate this behavior exactly.
So, for the time being (until browser vendors change something else), cookies can still work within iframes, so long as they have the
Secure flag set and use
There’s an ongoing thread about this issue. It’s unfortunate that you have to resort to allowing cross-site cookies or using local storage, but it’s something that’s only controlled by the browser vendors. We’re considering how we can make this scenario better and hope to have some changes soon.
