The big companies really don't seem to care about low bandwidth users.
I attempted to use Teams website once over a very low speed hotspot. It utterly failed. It just kept reloading the same resource over and over and over, maybe it didn't wait long enough? Not sure. But it never worked.
I then tried the teams app, and that was no better. It would get stuck on the main screen and couldn't go any further.
So then I tried outlook, desktop client. Total fail there as well, it couldn't seem to manage to download a couple emails.
I finally resorted to ssh and using a command line.
I feel like a old man screaming get off my lawn, but it really seems like the new programmers need to use old computers for a while and learn how to be more efficient.
