I wish the Logi+ options app would email me whenever my batteries are low. I have four devices on two separate dongles in two different rooms, and I never, ever see battery low notifications until the keyboard or trackball is critically low and they are blinking red themselves. I don't want to wait that long for the batteries to be depleted before starting to charge. For that matter, it would be helpful if the Logi+ app would email me when the batteries are fully charged, or even 95% charged, or some configurable amount. Back on the original program, before even the Logi app, I used to notice the battery low notifications mostly regularly. Now the notifications are non-existent even though I have always had the option turned on in the app. I've even tried turning the option off and back on, with no change. This has been like this on multiple PCs, both Windows 10 and Windows 11. Very frustrating, and Logitech's chat is useless for tech support.
