I'm using the Tapo app to monitor four Tapo C310 cameras on an iPad mini.

The cameras we purchased separately and added to the app in various stages.

The 4th camera would not connect to the router. The error was failed to get ip address. It is now connected through an extended successfully. I do not understand why it will not connect to the router directly as the other 3 did. The router is a tp-link Archer MR400. The extender is tp-link N300.

The app had taken up all spare storage and I could not do any system updates. The only way I could find to release the space was to delete the app and reinstall it. Prior to deleting the app it worked perfectly with instant viewing on all 4 cameras.

After reinstalling, when I use the grid view to see all 4 views, all of the cameras have a lag of up to 5 minutes which is totally unacceptable. If I select one view, the clock rapidly counts up to the correct time.

The problem is with the Tapo app. Version is 2.9.11. I have seen this reported by other users but never seen a resolution.

Also the app frequently crashes.
