Stick Up Solar Cam missing events

Hello, I'm using a Stick Up Cam (connected with solar panel) at my front yard for less than a month. I using this Stick Up Cam with 5min snapshot function. I saw several snapshots with cars etc. in the motion zone but I did not get any motion alert. Sometimes I get alerts from cars at my front yard but sometimes not people detection is a bit better. Furthermore I switched off the people only mode (never switched on this function) but if I arrive to home never perceive our car. I waited minutes in front of the garage and staring to my phone, moving back and forth with car but the cam does not recognise the motion until I got out of the car (I tried it several times). It is rather annoying because it is a security device and it should be work 100%. I linked this cam with a Doorbell 3. The linked videos works perfect and every time and the live video also so I think the connection should be fine. Sometimes in the device health I saw poor connection but I cannot accept this problem because I using Mesh system in my house every device works fine and my phones got also good connection next to the cam and doorbell (76,5/14,8 Mbps). So if the connection is poor it may cause there is poor antenna in the ring devices. This problem rather annoying and you want a piece from my salary for this service (3€/month/device) in every single month. This is unacceptable from my side. If the problem cannot be solved I will demand full refund and choose other company products.
