Did anyone ever experience any interference from other connected or paired Bluetooth devices (speakers, headphones etc.)? Meaning e.g. that not all the keys you type register? And you have to retype parts of most of the words? I am using a wireless Windows PC keyboard (with a wireless USB dongle) right now and the phenomenon is aggravating. Before I spend money on a new Apple Magic keyboard, I'm trying to find out if interference from other wireless/Bluetooth devices may be part of the problem or if it is just the incompatibility between the keyboard and my macOS 10.13.6 and/or hardware (2011 iMac). Any helpful comments anyone?
