I am trying to get a specific member profile from the API by filtering on a specific email address, but this:
GET https://api.squarespace.com/1.0/profiles?filter=email,first%2Bsecond%40domain.com
Returns zero profiles - even though I do have a member who has registered with an email address like first+second@domain.com - and from my testing, it seems like it's down to the '+' character in the email-address - all other queries return the correct profile - it only fails with email addresses that contain a '+' character.
Can someone please fix this?
