I assume that using Revolut on a mobile phone is fairly safe. However, I treat my mobile as UNSAFE in general. that is why I never put any important documents there with personal, sensitive information.
I understand the need of verification of my address or source of the income. But I’d like to send these documents in some other way, than from my mobile phone.
Frankly speaking, I had a hard time downloading somehow the documents ot my mobile, as I keep most of my documents paperless, digitized on a safe storage.
I needed to create FTP server on the fly, and connect my mobile to it in order to download the documents.
I consider this effort as totally unneeded, I should be able to send these documents directly from my PC to some encrypted webpage managed by Revolut.
Please consider adding such option to your system.
