Will the Android DJI Mimo app auto update itself or tell me when a new apk is released from DJI?
Or do I always have to go the the website to check if there is an update & manually download the latest apk?

Hi there. Thank you for reaching out. The DJI Mimo app will notify you once a new version is available for download and installation. Follow the prompt to update the app. If you did not receive any prompt and notice a new version has been released on our website, please restart the DJI Mimo and connect to it then the app will send the update prompt. Hope this helps. Thank you for your valued support.
