After painstakingly creating a number of templates in the MacOS version of Goodtask, I realized I needed to turn on iCloud Drive on my Mac and iPhone to sync settings and preferences.
After turning iCloud drive on the iPhone and then the Mac, the templates in the MacOs version of GoodTask were completely overwritten and replaced with the templates on my iPhone.
I do have Backblaze installed and it was current when this overwrite happened, my question is: where is the file that contains the original templates in MacOS when iCloud Drive is NOT enabled, and is is possible to recover the templates from that file.
You can set up templates inside 'Settings - New Task - Templates'. You can make template title and set up tasks that you want to create with that template.
After it's made, you can use it to add multiple tasks at once. You can long press + button and choose the template. You can long press on dates on calendar too.
