Hey @AmyF,
Thanks for reaching out and sorry to hear you're having trouble with Square Online and address validation!
While this is unfortunately something I'm not able to look into via our Seller Community forum, I recommend getting in touch with support for further help with this one.
You can call on 1800 760 137 (Mon-Fri, 9am-5pm Melbourne time) or email via this form . If Support are able to identify an issue they'd then need to file a request for our engineering team to investigate further.
Sorry I can't be of more immediate help here - I understand this is must be super frustrating for your business. Please message back to let me know how you go!
