Give it a few days for your itch downloads page to recognize it, it's happened to people every update. Itch's systems are just a bit delayed for updates.
Glad to help. Notably, I'm a $10 purchaser and have my download for 0.20, which is the version I should have access to. If you're in the $20 tier, my previous advice stands, but make sure you've purchased at the correct tier for the version you're looking for as well. :)
