iOS Volumio App keeps losing connection to Rivo

http://logs.volumio.org/rivo/mdbRR6I.html

I use the Volumio app on iOS 16.3.1 (app ver 1.4.2) and Android. The iOS version keeps losing connection to Rivo and I then have to restart the app on the iPad to able to control Rivo again.
The android app does not show this issue. Is this a known issue?
