Does BusyCal sync Settings between multiple devices?

Yes, it does, but not all settings are synchronized.

Most settings from one device, such as a Mac, automatically sync to another similar device. However, the following are excluded:

• Accounts and related information
• View-related settings. BusyCal's advanced filtering allows for specific view settings associated with individual Smart Filters. Enabling the "Remember view settings" option allows users to maintain distinct view settings per filter. Therefore, syncing these settings across devices would disrupt the filter-specific configurations and could lead to incorrect view settings on other devices.
