Script Manager not finding domains/sites

For certain pages/domains when I try to add GTM via script manager The lookup box on the right will not show the domain/site that I type in, has this happened to anyone else before or does anyone know why this may be?

Thanks

Hi Cameron, no I have not heard of this happening before on my end. It could be a bug. I’d recommend reaching out to the Unbounce support team directly for something like that to see if they know.

And welcome to the community!
