how can i unlock it in the app?

I already did that on 22Sep ,but still cannot use market.

Thanks for playing. How long it takes to unlock the Transfer Market depends on a few factors.

• Whether your account is in good standing and if you’ve ever broken the FC rules. 
• The number of Ultimate Team™ accounts you’re using on the same device.
• The number of active days you’ve played Ultimate Team™.

• An active day is when you’ve played three full matches in Ultimate Team™ and logged in to the Web or Companion App within a calendar day, following UTC timezones, per Ultimate Team™ account.
• Learn how to set up FC Playtime to check your time spent and matches played.

Here are some examples of how many active days of playing it takes to get access to the Transfer Market. 

• If your Ultimate Team™ account is in good standing and no other Ultimate Team™ account has been created or used on your device, you’ll normally earn access after playing two active days. 
• If your Ultimate Team™ account is in good standing, but other Ultimate Team™ accounts have been created on or used on your device, earning access will normally take at least four active days. 
• The more Ultimate Team™ accounts used on the device, the longer it might take for each account to earn access.

We’ll send a message to your Ultimate Team™ account in-game to let you know when you unlock access. You can also check the Web and Companion Apps.

Thanks, may be need 2 days, it unlocked....

Thanks for your patience! 😁
