Unsurprisingly, Microsoft Dynamics 365 is an absolutely shit app from the user side too. It's horribly slow, has a nearly unusable UI, uninformative errors, that kind of thing.<p>The expense reporting side of D365 is especially bad, or maybe it's just my employer's integration of it. It doesn't properly understand currencies or conversion rates, so maybe you'll stay at a hotel in Prague and the expense report page will say $20000 instead of CZK 20000, and then it will write a completely wrong exchange rate, and then refuse to accept the report (with an error in a bar at the top of the screen, but it's modal) until you properly itemize this incorrectly recorded expense down to the last haléř.
