We use Microsoft Dynamics 365 (model-driven app) at work, it's rarely mentioned on HN and people don't know how insanely bad this P.O.S. software is.
From the botched implementations of AG Grid to their crippled version of CKEditor (with Copilot forced in of course), the daily bugs are an absolute nightmare.
And then most support tickets (if you can even open one after a forced chat session with Copilot), get handled by a third-party, most likely in India with different timezones than you and the support calls are a crapshoot.
