My lynx shunt stopped showing soc %

My lynx shunt used to show soc, although it wasnt correct as i never got round to calibrating it properly, it was at least still showing the soc %, but now its just showing two dashes. I hope its not gone faulty again, as this is my 3rd shunt now, after sending the first two back.
Any suggestions?

Have you tried manually setting the SOC to xx % or synchronizing it to 100% … to see if the display works.
Have you tried an FW update?

Not yet to any of your suggestions, but i will try this over the weekend and let you know the results.

11.3.8. State of charge is missing

We had a sunny day today and my batteries charged to 100% and this has made the shunt show the soc again.
Thanks guys. This is such a learning curve but fun!
