I've had the same problem on Android. But clearing the cache and killing the app, brings up a welcome screen, but relays don't reconnect. Still shows zero relays connected. Under relays screen I see 7 recommended relays but the + icons do nothing to add them. If I go to Add Relay and type an address in, the Add button does nothing, except the X changes to a tick mark. My version is v0.7.6+56.
