Problems with Ring Security Cameras

To make this as easy as possible, I’ll suggest a design.  My house looks like a widened, thick  ‘U’ – open end facing up. On the outside bottom of the ‘U,’ are four cameras equally spaced across the bottom, numbered 1>4, left to right.  OK, I lied.  #3 isn’t a security camera, but a Ring doorbell.  On the outside of the left side of the ’U’ are 2 equally spaced cameras numbered top to bottom 5-6.  On the top of the left side of the ‘U’ is one camera numbered 7.  On the inside bottom of the ‘U’ are two cameras , one at each corner, numbered left to right 8-9.  Finally, below the ‘U,’ but not touching, is a Ring Mailbox sensor, numbered 10. Here we go.  I have the app set to change to ‘Home’ 10P to 6M.  Otherwise, ‘disarmed.’  With frequency, each camera will stop sending audible and popup notifications.  Number 1 is the most egregious offender – about a third of the time.  I can find no specific time or day for this failure, nor is it or any device failure associated with ‘Home’ or ‘Disarmed.’  I have walked under #1 and get audible/popup notification.  10 minutes later, walk under # 1 . . . nothing, and nothing for hours. When I walk out my door, #3, camera lights 1,2,4 come on.  I have none of them linked to the other. At night, most of the time, camera #8 turns on for 1-2 minutes, stays on 1 sec, and goes out.  Cycling ALL night.  Often around dusk/dawn, but sometimes not til 10P.  Rarely, it doesn’t turn on all night, BUT, when it does not come on, & 7 comes on and stays on all night.  No cycling on/off.  None of those cameras are linked. All the above cameras record events, even when the lights don’t come on or when they stay on or cycle. Finally, camera # 1 and Mailbox sensor 10.  I have them linked so, when the mailbox door is open, camera 1 records.  Works perfectly . . . fall, winter, spring.  Consistently sends notifications.  Rarely in the summer except at night or during rain.  This is strongly associated with amount of direct sun in the summer.  Mailbox door is in a brick mailbox pier with the mailbox door on the south side of the door. I suspect, putting an insulation on the inside of the door would stop the notification silence.  Would this work? Sorry for the long post, but I suspect these may be related somehow.  If I uninstall/install the Ring android app, will I have to reconnect all devices (I have more in the house)?  I’m close to 80 and can’t climb ladders for outside cameras any more.
