Unable to Receive Push notifications on Test environment

My push notifications were working all fine when I use Production environment. But when I shifted to Test environment. I’m facing “Unroutable” error. Description is as follow:
All configurations and profile data is same as is was in my Production environment. Please look into this problem ASAP.

Hey @zuhasohail18 - Try going to your push provider settings, copy the credentials you used for the production instance, and paste them to the test instance. Try sending another message from your test environment and see if that works. This could be an issue with the push test settings not having access to your push channel credentials.
