How to delete ALL alarms in one go in my phone without waiting 24 hours,

This is not possible at the moment.

If this was to be considered as a new feature, I would like to suggest that an option was available to delete all but the last ā€œnā€ alerts.
I am new to the application and find it very useful - thanks. Dave G3UEG
