Instagram/Facebook new selling rules! Urgent help!

Site URL: https://www.immyhowardmillinery.com/

Hello there, 

I am hoping to have some rather urgent help before 30th September, thank you!

I received a message on Instagram where I sell my products via Facebook business manager and commerce manager (using catalogues) telling me to ‘take steps to keep selling’ before 30th September. I have tried confirming my catalogue where all products link to the domain www.immyhowardmillinery.com, which is verified on Facebook business manager, but when I get to the section on Instagram to ‘confirm my website’ I cannot click anything.

As far as I am aware, my domain is verified using the DNS txt method.

I have a the personal plan on square space.

if anyone could help me,that would be so appreciated! I have attached screenshots of my Instagram messages. Does anyone else have this problem?

thanks x
