Pokemon Home has been updated to Version 1.04 on both iOS and Android devices. This update is just 25 MB, and the patch notes say it includes bug fixes. Unfortunately, no specifics on what bugs have been fixed were included.
My experience with the free plan has been rather smooth. I wish that when you mute the sound effects that actually happened. Also, if you can't send a Pokémon though the GTS, it shouldn't be an option to ask for it (I'm looking at you, Meltan)
