Install the txt as md plugin and activate it.
Close Obsidian.
Then open the .obsidian folder, then open the plugins folder within, and then the txtasmd folder.
Open the main.js file in any text editor.
Add markdown to the list of extensions. I attach image on one I’ve just done. It’s line 84.
Then save, then reopen Obsidian.
But remember this does not mean .markdown files are treated as .md, it simply means that you can read and edit them.
