You may have noticed a new setting Protect notes from unwanted edit
in the latest UpNote version on iOS and Android app.
This is to prevent your notes from being edited due to accidental tap on mobile.
To turn this setting on, please go to Settings
> General
> Protect notes from unwanted edits

When the edit protection is enabled, your note will be open in read-only mode. To edit it, please tap on the edit button on the top bar of your note editor.
