Emoncms mobile refresh error on iPad

I have 3 iPad and two iPhones. These are all running Emoncms mobile 1.2.3.33 and IOS 15.5.

One iPad is devoted to run the mobile app 24/7 and recently when set to display both solar and consumption it fails to update both but displays either just the solar or just consumption. The next refresh then correctly shows both. This problem has only recently occurred although exactly when it started is not known.

A power cycle of the RPI did not improve the issue.

The problem can be seen on all three iPad but does not occur on the 2 iPhones.

This is a trivial problem but @mattjgalloway may be interested to comment
