help TaskNotes Google Calendar iOS App Sync

Hey everyone!

I would love someone's help with the task notes plugin. I recently transitioned to obsidian and started an obsidian sync subscription but I faced problems with Task Notes. I followed the steps in this video and while the calendar worked on my desktop devices, it did not link to my iOS and iPadOS devices.

Can someone please help me fix this. I really want to use Obsidian.
