@buddy426 Thanks for contacting the forum! As you can see, a great place to come for advice and troubleshooting suggestions from other Forum members.
You guys have covered a number of the suggested troubleshooting methods for the SD card, awesome. I am curious @YorkshireUser as well about why it would be happening to both cameras…
This may sound silly but double check your internet connection by the cameras. Make sure there is no problem there. And, try a different SD card if you have one and see if this is repeating with the new SD card. If not, eject the cards tonight, do a hard reset on everything, uninstall & reinstall the apps, and let us know how it goes.
Thanks for your patience! And, thanks for being a great moderator @YorkshireUser!
