Templates Missing in Pages
I have Pages vs. 11.0 on a Macbook with Big Sur. I can no longer open templates in Pages. I want to print an envelope. The only template that opens is one I created in January, 2021. It doesn't matter if I click on the icon Pages in the dock, then click on New Document, or if, while the document is open, going to file and clicking on New.
I followed the instructions to open the Template window in Pages, then opening Time Machine. Time Machine only recorded from yesterday, April 16, 2021, nothing earlier.
How can I find the envelope template in Pages?
Thanks
MacBook Pro 16″, macOS 11.2
