No updates for 3 weeks now

Looking for some help on this one. I have a GPSMAP 7410xsv unit paired to a Google Pixel 5 and a Lenovo android tablet.

Have not had any ActiveCaptain community updates since 2 August. Away from the boat the ActiveCaptain app on both devices reports that I need to load a software update (2021.0617.0) . When I get to the boat with either device and connect to the plotters WiFi hotspot - it says that the system is up to date - no updates needed. Plotter reports it is running V20.40 plotter software and v4.40 sonar.

I have deleted and downloaded the update software on both portable devices - but no difference. When I start ActiveCaptain on the plotter it reports that there were errors in downloading ActiveCaptain community updates.

So 2 devices want to update software on the plotter and the plotter doesn't want to - any ideas?
