Then it doesn’t happen. It’s highly likely the Templater plugin. More specifically, template hotkeys. They somehow get triggered on mobile. But I use them a lot on desktop. Can’t I turn them off only on mobile?
What kind of Templater templates are you using? Normally Templater should only be run when you actually insert a template, with one exception and that is that you’re using some variant over the <%+ templates. This could be run, and re-run in some cases (both on mobile and desktop).
But all the “normal” template stuff, like <% or <%*, should just run once, and be done with it. Are you having dataview queries in the note you’re experiencing this with? Are you in live preview when this occurs?
