These types of licenses are still supported. I believe you might just be running into an extension of the bug that was recently fixed. The top of the newest update on the blog (https://www.autodesk.com/products/fusion-360/blog/june-4-2019-product-update-whats-new/) explains this a bit.
From the post: "We pushed a small update today – apparently there was an issue where Fusion 360 wasn’t showing you that your license has expired, even though it was actually expired, so we just went ahead and “fixed the glitch”. With that said, this doesn’t block you from using Fusion 360, but you’ll need to re-subscribe or renew a license to save your work. Click on the “Buy Now” button and that should get you back on track. If you’re having trouble with this, get with our support team or post in our support forum and we’ll help you get sorted. "
