One of the calendars on my Google calendar isn't syncing correctly. It's one that I downloaded online and have been using for years, but now it won't sync events past December 25. It can see the whole thing no problem when viewing from a website and had been using it successfully for years. I tried un-linking all calendars, but personal and downloaded, and re-syncing them, didn't resolve the issue. I tried downloading a similar calendar from another site, also won't sync events past December 25. None of my other calendars that are synced to my phone (Galaxy S6) are having this issue, all are syncing for months past December 25. Anyone else ever had this issue? What can I do to fix it?
