I am guessing that if you do not have an Organization > License Info option, as you have shown in your screenshot, that this may be a "Legacy" Systems Manager license in a Systems Manager only Network with no other Meraki devices/licenses. But regardless which license type you have, let's consider it "unlicensed", otherwise you should see a License Info page. Call into the Meraki Support team to confirm. Even if you are unable to technically receive Support (on an unsupported version) they'll be able to confirm for you. Do you have any other piece of Meraki hardware? I'm guessing you have no physical devices in your inventory if you look under Organization > Inventory. If you do have even a single piece of equipment (even a free AP you got from attending a webinar) that you can add to your organization inventory, you'll get that License Info page to show up. And at that point you should also be eligible for email support.
It is correct that with the latest licensing, Meraki offers a customer-initiated Free Trial, fully featured for as many devices as you need (even over 100) for 30 days with full support, and it's very simple to convert that to paid licensing model if purchased. I'd agree with other posts (here and on other forums) that Meraki has understandably evolved the licensing model (to the only two options today, temporary free trial or paid version) as Systems Manager popularity grew along with the development and support teams. If this is going to be for home/personal use for just a few devices, unfortunately there's really no SOHO (free) license option at this time. Keep in mind while the only version is ultimately a paid one, it it one of the most full featured enterprise EMM products available, is 100% software so requires no on-site appliances, works with any vendor’s network infrastructure, there's no training required, and the licenses you do pay for are device agnostic, one license per any type of device with options for 1/3/5/7/10 year terms, and provides full email and phone support 24x7x365.
