I use the Magento 2 CMS. It’s known for displaying an error to all browsers/devices “(Invalid Form Key”) if the web server PHP value of
max_input_vars is too low.
For some reason, after implementing Cloudflare, all iPhone and iPad Devices see this error. It cannot be recreated on an Apple Computer, Windows PC or Android Devices.
Is there some setting in Cloudflare that I can tweak/enable/disable that would result in solving the issue with these 2 Apple Module Devices?
