Error when adding Suica: "The system is busy"

[Dalet_]

I can't add Suica to my Versa 4, after filling in my name and phone number, and choosing an amount for the initial charge, I get this error during the "Dowloading Card..." step:

Error

The system is busy, please try again later.

I've tried every day for a week so the message is clearly wrong.

I have already contacted support a few days ago, they said they escalated and that I will get an email later. I haven't heard back since.

Update: Support has replied confirming it's a bug, and said to try again with the new app version 3.71

Update 2022/11/25: I have 3.71 now but it still doesn't work. I don't have the new firmware update yet (the one for Google Wallet) so maybe that will fix it

Update 2022/11/30: I installed the new firmware update, still get the same error message. Waiting for another answer from the support.

Did this end up working for you? I'm on the latest version and still having the same issue..

I also still have the issue, the new app version 3.71 is out but I haven't gotten the new firmware update yet (the one that adds Google Wallet and Google Maps). I'm hoping the firmware update will fix it.

Update: the firmware update did not fix it

I've finally figured it out.

You need to use a Japanese bank card when creating or adding funds to Suica. I get the error only when using French bank cards on Google Pay.

I used a virtual LINE Pay card since I don't have a physical Japanese card.

For US users: an American Express card also works. There is currently a known issue with Suica failing to charge from non-Japanese VISA cards. This affects people who use Suica on Apple Pay as well. I tried Mastercard with Fitbit and it didn't work either, but I don't have that many to test with (almost all of my cards are VISA). Amex worked immediately.
