I can't msg you in private unfortunately.
This app will not work anymore. The firebase db was deactivated. The current mod version is v2.8 and is still for sale, so I won't post the anyhax panel that I modded and that no longer uses his server to encode the response, and will work even if the api key isn't in the whitelist. I so if you want implayer you will likely need to pay for it for now. Also the firebase could be deactivated for v2.8 any time the dev wants., So it likely won't end up being passed around in forums for awhile if ever.
