this logitech options + is total trash , crashes wayyy more than regular logitech options which i was forced to updrade to since my device was no longer supported every time i turn around and try to use app specific button layouts for my mouse it isnt working typically needing me to manually open logitech options + let it fully load clickmy device then click the app specific profile before it will operate as intended . and thats if im lucky , currently no matter what i do it will not change my mouse inputs . so im left with no option but to TRY restarting my computer and while i assume it will restore proper function it is still very annoying, force me to use a less stable version of your software , good on you that will help customer satisfaction . aside from that im connected through the provided unifying reciver and when i check for updates in the app settings it says no device found so im connecting your product thrpugh your product that came with this exact mouse yet it cant find it . yeahhh good program your forcing upon your customers .if you wanna let me use a program for my mouse make it g hub not this pile of flaming garbage . i thought you guys were better than this been a customer for years , might see what razers up to these days
