Default OTA Update

Hello guys, i rooted my device like 3 months ago and i felt like it really disabled my OTA update. Whenever i checked for such, it always says my system is the latest version. My question is, HOW DO I KNOW IF MY OTA UPDATE IS STILL WORKING OR NOT? I've searched for answers for like days. I think maybe its time to ask for answers here.

Your replies are well appreciated. Thanks in advance. :cheers:
