Open Editions are not shown on other platforms

I have created 4 claim pages for open editions. The first one was days ago, the last three - this evening.
These last three don’t show the option to be viewed on other platforms.
I have an Open Sea account and only the first Open edition is visible there too.

Here the three links:

I can’t send the third link cause I am a new user.
