As per this report from July it worked before. So first I would try is going to Settings
➔ Security
➔ and toggle Allow native code debugging
either on or off depending on which it is right now.
Also according to the report:
initially, it did not work, even with Google Play Services installed: the app loaded, but after the initial screen, it never showed the identification/authentication/setup process. However I'm almost certain it started working after I gave Google Play phone and SMS/text messages permission.
So that is something to try as well.
EDIT: Seems like it might be an issue with Payconiq based on the reviews on Playstore.
