Hi Ollie,
I think is a redundant request as we did all this six months ago and shopify could still not fix anything, telling people to delete there cookies and cache achieves nothing and does not help, and your “support team” came up with nothing no matter how much info we have given you and told us that they dont know what the answer is but in reality the obvious answer is safari (and some other search engines) on mobile devices simply does not now work on our shopify site and many others yet with google chrome it works fine.
The only real question is who is at fault is it shopify or safari (and others), it would be good if shopify could come up with an actual fix or at the very least be open to customers and tell them that they cannot fix the issue so we can inform our customers and stop losing sales.
