Hey all!
There's a fix in process that will have the Listing page in Shop Manager back to normal shortly. Keep an eye on this thread for an update when the fix is live.
Thanks!
Just got an update from the team that the fix is live! I loaded up my shop and the Listing page is loading, so everyone should be good to go at this time. If you're still seeing the blank page, please clear your cache and cookies to assure you've got a fresh connection before trying again.
Thanks!
