This is becoming more of a hassle and a nightmare than anything. I downloaded logi options+ because I wanted to have further button and gesture customisation, but it's become impossible. Sometimes the functions only work if the app is open, others even that doesn't work. Additionally, my K780 is not supported yet, so all my mixed devices shortcuts are useless now. I can't make them interact with each other and it fails progressively. Please fix this, I always make do with something or fix it myself, but this is beyond me at this point.
