I have had Fantastical now for 2 weeks and on occasion, I'll have the watch and the phone both fail to notify me of a reminder or a calendar appointment. I have tested the issue with both calendar and fantastical on and with each one off while the other was on. I found that the native Calendar app always notified me every time, where Fantastical sometimes wouldn't at all. Anyone else see similar issues? I am assuming that because native 3rd party apps aren't supported that this is just the nature of the beast for now.
