I searched for this question and could not find it. Apologies if it has already been asked.
We use M2E Pro on Magento 1.9. In May of 2018, eBay announced that they are changing their website, and eBay seller stores to Mobile-Responsive Design and improved SEO (source: https://sellercentre.ebay.com.au/SU18-1/eBay-Stores). Unfortunately the eBay FAQ does not mention how it works when you use an extension. We have tried contacting eBay, however they could not help us and did not know what to do in our situation.
Can I please ask - how would we make our eBay products, and eBay pages Mobile-Responsive, using M2E Pro? We would really like to make our eBay store Mobile-Responsive, and take advantage of our current capabilities.
