I've been using the Windows app for years now, and decided to purchase a subscription so that I can use the web based recipe builder. The issue is that after I've entered my equipment specs. I head to the recipe builder and the mash strike volume and temps aren't calculated. On the Windows app it's calculated using the absorption, l/kg, grain temp etc. I've fiddled everywhere now and it doesn't calculate. Here's an example of a test recipe that I am using to calibrate the online one to match the Windows app.
