Tried all the steps as described in the troubleshooting manual: reset pincode, reinstalled victron connect app, removed shunt from electrical system and reconnected it again. Shunt is recognized and light on the side of the shunt is blinking. Light stops blinking and remains on when reaching 95% for a few seconds, but then fails to connect fully. I can connect to other devices like a SmartSolar an Battery Sense.
Tried with another phone and was able to connect, but would prefer being able to connect with my own phone.
