I faced the same issue today. All the text from yesterday’s daily note disappeared.
I had just copied some of the open to-dos from yesterday’s note to today’s note. Then in today’s note I clicked on Yesterday’s note link (I have set up each of my daily notes to have a <<Yesterday | Tomorrow>> links at the top).
Instead of going to yesterday’s note (which was pinned) It opened another note for yesterday, and this note was was blank. So for a while I could see 2 notes with yesterday’s date - one with content and another without any content.
I thought it was a random issue, and closed and restarted Obsidian. Now there is no content in yesterday’s note.
I am not using “reading time” plugin. However I do use “Andy Sliding Panes” and also “Templater” which I use to create the headers and the <<Yesterday | Tomorrow>> links in the daily pages. And yesterday I also enabled “headers sync” plugin.
Could it be a clash with Header Sync and Templater? Even of it is, why should the note content vanish?
And is there a way to recover the content? I have a lot of content in the daily notes.
I am in the process of moving from Roam to Obsidian, and had thought that I would never lose content in Obsidian (which some people have lost in Roam - though I have not) and this kind of defeats the purpose…
Thanks in advance for your help.
