Clients having to create an account to view file

When sharing a file to a client (not a prototype) they are forced to create an account.

I have selected ‘Anyone with the link can view’ but I’m still getting feedback that they’re having to create an account to view. I try it in a private browser tab on Safari and I don’t have to create an account so I’m wondering if some browsers make you create an account and others don’t.

Does anyone else have this issue?
