Cannot sign into my.smartthings.com

Hi had a firmware update on a Matter Hub and suddenly all the devices were removed from SmartThings. And re-added. Now I can’t add anymore devices. The app says I’m over the 300 limit. And I can’t sign into my.SmartThings.

I’ve not added any actual devices so shouldn’t be over the limit.

An unexpected error occurred

Sorry about that.

It’s fixed itself. I now have access again.
