11 of 17 cameras show offline but still detect motion, notify, and record

11 of my 17 installed cameras have gone offline in the Arlo Secure app (the remaining six are still operating). They are a mix of Essential XLs. Although the cameras show as offline, they still detect motion, notify, and record to the cloud.  They do this even when the mode they are operating on is switched off; the individual cameras themselves cannot be switched off because they show as offline. The cameras also show as offline in the Arlo website. This seems to be a software problem. There are some older posts about similar problems that suggest that the Arlo development team was working on a fix. Please advise any fix, especially any fix short of trying to reset all of the offline cameras because some have posted about issues in adding them back. Thank you.

Try rebooting your router or hub to see if that helps.
