If you're still experiencing the same problem:
a).Check if you're using android 4.1+, if not then its not compatible
b).Check if you app is on the latest version 6.8.1, if not, Update it
c). Clear data and cache
or did you change your apps permission/s?
And your last resort is to obviously contact their support. Users above already provided some links. Make it concise and should be followed by proofs e.g. screenshots
Hey,
Thanks for the reply. I tried to delete all data and re-install app several times with no result.
a) I'm using Android 7.0 with MIUI 8.0 (phone - Xiaomi Redmi Note 4x)
b) Yes, I'm using 6.8.1
c) the same as (a) - I cleared it several times
No permission/s were changed.
I contacted their support 2 days ago, but all I got is their template reply about re-installing the app. I also asked their support via Twitter.
Cheers!
