I use it on windows. The client is totally fine for the most part.

Though for some reason it regularly screws up the device-connection, forcing me to reconnect the device, loosing access to every old message. Seems to be a rare bug though, as my family also uses the windows client and theirs never has this problem (out of 8 device 1 has this problem)

Yeah, but those subs contain the majority of redditor interaction. ~70k people on a sub is enough to put it into the top 5%. The top 1% subs are very likely responsible for 50%+ of all reddit posts. Losing just a handful of them is a big deal.
