The media player is software. Your account, playlist and content access are separate. Confirm which part you need help with before changing a working setup.
Choose the correct app edition
Use the official developer listing and check its supported device. Similar app names do not prove the same publisher or features. This independent website does not provide the official Smarters Pro app or sell its app licence.
Match the account input
Ask support whether your chosen player needs a playlist URL, account fields or a portal. Copy the full address and any case-sensitive values carefully. Do not publish screenshots that show tokens or passwords.
Test before adding complexity
Start with one stream on one device. Check live playback and an on-demand item where available, then configure guide sources, favourites and subtitle preferences. Confirm app-licence conditions with the developer.
