I checked their online support and followed the steps, still was not able to do it, it won't open your publication page, neither from Safari on my phone nor Chrom on my laptop. I've created a support ticket and sent them a screenshot. I'll let you know what they will say.
I see. I'm not sure but ill try again. I've tried from the app it said the same thing. I'll try again.
If it keeps failing, please follow up in an email! I can get Substack's folks involved.
