Landed here after a search for fantastical watch syncing issues. I have the fantastical complication on my Apple Watch face. Every time I glance at it, it shows me no upcoming appointments. This, despite the fact that I have a full day of appointments lined up. The only thing that will get the fantastical watch app to refresh is to open the app on my phone, something I rarely do to be honest. This is completely useless. All these things are supposed to sync automatically in the background. This would be crap for a free app, let alone a paid one from a company that expects people to pay a recurring subscription fee.
