@unamis76 , no updates?
I've got a problem of my own for almost two days.
I have 1** something euros in the euro account but when I go to transfer to the card the option for "add to funds to card" is most of the time not visible. Restarting the app does nothing, and when it finally appeared although I transferred the money and immediately after the message funds sent from the account to card account I get an instant message saying the opposite.
Getting annoying, I would understand an error for a few hours but days???
Sorry that you're having issues as well

The updates are that there are no updates, really, I've been reminding support day on and off about it and they have nothing else to tell me. They just copy paste more or less the same message saying their banking partner is tracing funds. So they are either:
A: Doing nothing, or
B: Making heads roll at their banking partner, I have no way to tell which one of this is true.
I've tried reaching out to the banking partner, and no reply. I've asked Wirex's support for a phone number from them that actually works and they've not provided me with one, both annoying and very fishy.
That being said, I do want to believe they're not doing some kind of exit scam. However, I have already filed a complaint against them because this is taking too long, and it is simply not acceptable. I'll gladly withdraw the complaint if this is solved asap. If it's not solved, well, I don't know really, but I know I won't stand still.
This is a different issue from mine but does seem to be what stompix is complaining about. But may be a good idea raising awareness of these troubles on Twitter as well.
