Whenever trying to log in (after already logging in), I get Xbox error 0x87DD0005. The only fixes I've found are to uninstall, restart, install and log in again. This is a very tedious process and doesn't work 100% of the time. This affects all of my other Windows devices as well.
It's not related to Xbox services, the rest of my Xbox-based games work fine. Try again and Switch accounts doesn't do anything except error out after an account is added.
