Do I must update API version before publishing app?

I want to publish my application. However it was been rejected by some reasons, that includes a reason related API version: “Your app is using an API version that is about to be deprecated”. I see that API will be deprecated at at least 5 months left. I want to ask that do I must update API version before publish app? Or just is a recommendation?

Hi @LeeHLD

I recommend updating your app API before trying to publish it. We are encouraging all developers to update their apps before the final deadline to ensure that apps continue to work as expected across all merchant stores. If you have additional questions about this please reach out to our partner support team from within your partner dash.
