When deleting events only one page, meaning one screenshot full of events delete themselves, could you have perharps a selects all for the entire day worth of events?
When you click the icon on the far top right of the screen which allows you to delete events there is a Select All at the top right corner of the screen in the Eufy App which allow you to select the entire days worth of events or you can select individual events to delete
It still only allows you to delete that one day. You have to remember to do this daily or once a week max otherwise you very soon have loads and loads and loads of videos stored and all have to be deleted day by day. Unless anyone can offer me a better solution?
