I have an original site URL approved by FB but I have had to create a new URL due to legal issues on the name and move the original URL to subdomain. The original URL is still the shop management site. Google Merchant, FB, IG and Pinterest now won't allow the Flexify feed because the flexify feed is a slightly different name from the newly authorized URL. I can't run two Flexify URLs, seemingly.
Has anyone experienced these inventory connectivity issues and found workarounds? I have tried the CSV approach as a short term but the files have over 200 lines so Pinterest won't upload it.
