Please do not create topics asking how long it will take for support to reply to you. Different questions may take different amount of time to respond, typically we will respond within a 1-3 days but it may take longer depending on the type of issue. If you haven't already, search for existing topics or check to FAQ to ensure that your question has not been answered elsewhere. To ensure that you request is tied to your account and prioritized appropriately, please contact us using the email address you have connected to your account. If you still need to make a topic about a Support Request, you must include your ticket ID with your message.
Hope this helps.
