Thanks, but unfortunately it does not seems to be the problem. I confirmed that the apps has all of it's permissions and i was on Wifi (i also have a mobile connection as well).
If this should be an automatic process, at which point is the firmware version checked and determined if an upgrade is needed? During the startup of the app? Does it routinely check in the background? Is there any way for me to recognize if the image was even downloaded in my phone storage (maybe i can check a specific directory)?
Is there an official yeelight app for windows? I've only been trying with an android device. I did come across some other post of someone also having difficulty upgrading via android.
