I was trying to set up Google channel. When I clicked Create New, the popup window’s size got cut, and only the title is left, I’m not able to proceed to next step, since I cannot see the next step from the popup window.
I’m not sure if this is the problem of Shopify or my Chrome setting.
I appreciate that you have included a screenshot of what you are seeing from within the Google Sales Channel, as that is very helpful! I would suggest attempting to clear the cache on your browser and attempt to setup the Google sales channel once again. If the issue persists, you can then attempt to use a separate browser - as for example, if you are using Google Chrome you can try this action on Safari or Edge.
Let me know if that clears up the issue, looking forward to your response.
