With Transferwise, one day I logged in from a new IP address (in Western Europe) and that seemed to trigger a requirement for me to re-upload identity documents. The web-pages to upload identity documents did not work; the process would get so far, then just stop working. I contacted Support, Support were unable to grasp the situation, let alone help. I had 30 days before the account would be terminated for not uploading documents. A couple of days before that happened, I tried again, and now upload worked.
