Hi, I’m using the ManagerImages but clearly the wrong way.
My apps constantly create new images with ManagerImages.createImage() but the images live forever in Homey. Is there a best practice to do this? Is there also a way to delete old images?
See this issue of one of my apps here:
They will disappear when app got restarted.
Hope restarting the app after every game will not be the solution
I have done it this way and only have one image (album art) per device which is changed again and again.
