How many users can subscribe to ChatGPT using the same payment method?

I heard that since last week, due to security concerns, there have been restrictions on ChatGPT Plus subscriptions for multiple users using the same payment method.

However, it is mentioned that the restriction applies when “too many users” use the same payment method, so I am curious about how many people can subscribe to ChatGPT Plus using the same payment method before the restriction is applied.

Is there anyone who can provide more information on this?

same issue I am facing. please share if you find any solution
