problem with switching layout bluetooth keyboard iphone

Hello. A few years ago, probably during one of the iOS updates, I encountered an issue with switching keyboard layouts on a Bluetooth keyboard, which still hasn’t been resolved. The problem is that when I press Caps Lock (which I use to switch layouts), the keyboard layout change happens very slowly—I have to wait about a second before the letters I type appear in the other language. Additionally, when switching this way, I not only hear the name of the next keyboard layout but also a notification that Caps Lock is off, which is somewhat inconvenient. Overall, the situation is such that I can comfortably type texts in different languages only on a Mac, while on iOS, due to this issue, it takes too long.
Does anyone have a solution to this problem? I would be very grateful.
