I do not know why this is not still working on Android, but it works on the web:

Chipper cash is low key doing daylight robbery against Nigerians. In addition to their unfair exchange rates, they also charge fees on top of that. I stopped being a user of their service after I was locked out of my account and when I got access, my dollar card was deactivated like yours. Very terrible service.
This is the kind of ugly experience that the FG has subjected Nigerians to. p2p is still preferred evn though you've to doxx yourself.
A user brought up a thread this forum about the restriction lifted by Wema bank:
