Hi @Jabba1,

Could you try clearing data for the Clock app and see if this still happens after doing so?

This can be done in Settings > Apps > [menu] > Show system > Clock > Storage > Clear data.

Note that this will remove all settings for the Clock app so you may have to set up your alarms again after clearing data.

Hi there, tried your suggestion that didn't help,then I realised the smarter app permission for the clock was off & that fixed the issue.
Thanks for your help anyway
