fbssupport - we were told the same false claim a year ago when we were considering signing up. Fortunately, we refused to sign onto a paid plan until the funcionality was live. It creates a huge level of distrust now with the company. I’d bet money if your a “new” customer inquiring about this - the sales staff would say it’s “coming soon” to get the contract signed.
We are, as some others mentioned, checking out Zoho. They have mobile ticketing, not quite as clean an interface but a solid app for creating, managing, and closing service tickets. Not sure why building this out would be such a significant project for Hubspot - even a responsive design of the page would help tremendously. Seems like something a single programmer could bang out in a few weeks at most.
