How long can I use the latest version for free after my annual subscription expires?

You are only given free access to each version for which you have paid for 12 consecutive months since its release.

So if your annual subscription started e.g. one month before 2023.2 was released, you won't be able to use that version when the subscription expires because paid subscription only lasted for 11 months for it. You will need to either pay for another month to get the fallback version for 2023.2, or use the previous version covered by the subscription.

您指的是永久回退许可证，并非我的本意，我的意思是：我已知道我目前的永久回退许可证是2022.2，但目前我还可以使用2023.2.1（我已于2023.08.29到期），我想问的是我在不续费的情况下，还可以免费使用多长时间（2023.2.1）。


Fallback ver.: 2022.2

Billing date: August 29, 2023 for $41.00
