Correct the class no longer required removed in OSSN 6.2 use component v 8.2

This is what I get once I enable this component on OSSN 6.3. All the required components are installed and I'm able to click the button to enable it. Please advise.

Error: Class "OssnSystem" not found in /var/www/xeira.xyz/components/MobileSDK/classes/MobileSDK.php:11
Stack trace:

The whole site stops working right away. The only way I found so far to fix it was to delete MobileSDK directory from components.

i install mobile app and whend try to log in say ”wrong api”.

Update
I was able to download the phone app.

Curious if the app is branded to your site or able to. Are you able to upload it to play stores as yoursite app? What all features does the mobile app provide?
