XP9CXNGPPJ97XX seems to be the new version of 9NHT9RB2F4HD, the Consumer Copilot application that doesn’t support work or school accounts. It’s the one that MS forced out for a bit at the end of 2024 but then pulled away from.

9WZDNCRD29V9 is “Microsoft 365 Copilot” which is the re-badged “Microsoft Office Hub” app meant for work or school accounts.
