I have just installed the PayPal iOS app on my iPhone Xs, running iOS 14.4.2.
After installation on a freshly rebooted phone, the app opens normally and shows the splash-screen with two buttons at the bottom of it: "Log-in" and "Sign-up". I am a veteran user of PayPal so - Log-in. This takes me to a page with the two expected fields: "E-mail:" and "Password". I fill the correct credentials and the page changes to a new page titled "A quick security check". On the page's upper half I see the PayPal logo and the text: "Security Challenge". The rest of the page is utterly blank! There is no security challenge to respond to, nothing! If I let the phone go to sleep and reawaken it, the "A quick security check" page acquires, magically, a new feature: at the bottom of the page there is now a fill-able text-box. I can type any string in that box but I do not know what it expects to receive!
Note that my PayPal account is set up to demand a one-time code, generated by an authenticator such as the Google Authenticator or similar app. That works perfectly well on normal web-browser log-ins. I did try to use the authenticator time-code in the text-box I described above, but that is clearly not what that expects.
I have also deleted and re-installed the app, for good measure. It did not fix it.
The app does not allow me to complete the log-in process. Please, help.
