If you've recently renewed your Tinder subscription, this won't affect your Boost wait time. The 30-day wait period is based on the last time you used your free monthly Boost, not based on the renewal of or re-subscription to Tinder Plus, Gold, or Platinum.
Once you’ve used your free Boost, you'll have to wait 30 days before you can use your next free Boost, unless you choose to purchase a pack of additional Boosts.
