I have tried so far closing the app, signing in and out, restarting the phone and reinstalling the app. None of it worked.
If I delete an webapp instance and login again from that location it immediately shows up again, so it has something to do with the windows phone app.
Thanks for the help.
I changed phones recently and the new app says:
'This device is pending approval. Login to the WebApp and approve it from the account devices page.'
If I got to https://my.pulseway.com/main/account/devices there is no device to approve.
Am I doing something wrong?
