I used it with iOS and had almost sent it back because the Cyrillic layout didn't allow me to place the dot, comma, and "" where they go. If you press the period and comma keys on your keyboard at the same time, you'll get "/" and "?" here. According to some online sources, the combination of shift + 6 and shift + 7 is required to type both a dot and a comma. After three business days of emailing technical support, I received a response: alter the layout in the operating system. And it's true — when this bluetooth keyboard is connected to the iOS device, the "main-keyboard" menu item expands to include "physical keyboard," with "auto" as the default and a number of Cyrillic layouts, including "2022 - PC" — select this layout, and everything goes back to where it should be! The period and comma buttons been moved to the bottom right, like on a computer, while the tilde sign () has been moved to the upper left. Hooray!
