Hey, sharing limits across projects is still there; it works the same as before, just with a slightly different UI.
Let’s say you bought an agency package with ‘40 premium websites’. What happens in the backend is your account receives 40 subscriptions that can be used on a maximum of 40 different projects each. Alternatively, you can create only 4 projects, for example, and use all those subscriptions to increase the limits of those 4 projects. Nothing has changed except the UI. Now, you can create 4 projects and assign 10 subscriptions each.
But you don’t have to do this manually. You can assign only one license to a project, and if that project hits the limits of the one subscription you assigned, we will automatically try to apply another LTD subscription if available. If not, we will notify you to upgrade that project with a monthly plan or to buy a new LTD if they are still available for sale at that moment.
And for pro pre-rendering, we will enable it for Agency Plans, but not for individual plans that we were selling for 59$. Reason behind this is simple, pro pre-render costs us and we can’t just give it for free to everyone, it is a completely new system that wasn’t even part of a plan until recently. But we will create an option to those plans to buy pro-rendering if they need it.
But before I dive deep in more explanation, standard pre-rendering that all plans have (even free ones) is still top quality and you don’t have to worry about your SEO ranking.
We will always keep promises to give all the features to all LTD plans that don’t costs us anything, such as collaborators, multilanguages, unlimited pages and more. But if specific new feature costs us money directly on a monthly basis, we can’t include it for free unforunetelly. For example, tomorrow when we launch AI that is working based on Open AI API, we need to limit quota for all plans, having unlimited quotas for free to all LTD plans would put is in ground. 
In general our pre-rendering system is getting big update really soon, and indexing of websites will be faster, and tools such as ahrefs, semrush and more will be able to read content as well without issues. As of now, these tools are not supported, only search engines are.
The difference between standard pre-render and pro pre-render lies in caching. Websites on standard pre-rendering will not have cached results; rather, when Google tries to crawl, we generate HTML and send it to Google, which usually takes 500-800ms, and that’s still amazing!
Pro pre-render will have those results cached and will serve what search engines need in less than 50ms. This will significantly improve the crawling budget of search engines. The impact of this will become clearer over time as people start using it and we gather more data. However, from our research, Google tends to rank higher those websites that are more optimized and on which they spend fewer resources to crawl (crawling budget).
