Why is my custom app not installing on my live store?

I am creating a custom app for my store
After creating merchant url I am unable to install in my live store.The button is disabled

There are no errors shown as well, Am I missing something here ?

Same issue is posted here: https://community.shopify.com/post/1334140

This seems to be a recent issue (within the last 24 hours). Hopefully This comes to Shopify’s attention sooner than later because as of now I do not think they know about it.

Has anyone heard an update on this? Experiencing this issue as well on a custom app I need to install ASAP
