Does a good job cleaning the air. Doesn’t always automatically start and stop based on the schedule I set up

Still waiting for some real instructions on using this app. I’ve written to the email and gotten a few responses with instructions that still don’t work. Then they stop responding. If you look around on the app, it has things to click on that look useful, but when you try, they are empty, or dead ends, or just don’t apply to anything. It’s the same thing with their website, “Dayette.”The website was created with Wix, which is a program so anyone can make a website, but apparently it doesn’t have to work. It’s a facade of a website, and app. Nothing works, nothing makes sense. I’m so frustrated with these appliances that can’t be programmed like they say they can.

Can’t set up back to back schedules. Machine turns off when one is done. Can’t set up a time starting on one day & ending the next. For example, 9pm-noon. Says start time must be smaller than end time. It runs on military time. Can’t get help when select help in the App Store. Can’t get help by emailing GCZ company either. Can someone explain to me how to set up multiple schedules?Edit-after contacting GCZ, the schedules started working. Now, the machine runs for a while then just stops. Wish you would correct the issue with an update!

I can’t find what filter I am supposed to use
