The issue surfaces when "fetching" email addresses from a website. From the iPhone using the Edge browser to reach the website & a particular feature, the website 'returns' a message to the browser requesting it to open the mail handler in order to launch an email. In that request, if there are more than one email address, it seperates each with a semi-colon (the delimiter). For example - addressA;addressB;addressC. The mail handler on the iPhone (or iPad) doesn't recognize the semi-colon as a delimeter and treats the string as a single email address, thus causing the failure. In my contact with Apple Support, they've acknowledged that THEY (Apple) do not (yet?) support the semi-colon delimiter. This issue, as far as I can determine, is APPLE only as all other devices (including Android smart phones & tablets), do handle it correctly. Searching the Apple user forums, I find first mention of exactly this issue back in 2007, but yet Apple has not resolved it! Since that's a 15 year period I'm not hopeful they ever will, but wondering if anyone "out there" had any ideas?
