synchronisation failed because of a network problem

hi all
v1.324.76 on android 6.0.1 (z3 compact).
Getting error when app is started - "synchronisation failed because of a network problem".
Network is fine because twitter and emails work.
Successfully connected to Google Fit - I can see 7 minute workout history.
Tried disconnected and reconnecting.
Think error started happening after I entered my weight directly into google fit, rather than through 7 minute app.
Exercise history is recorded in google fit, just not weight updates.
Thanks,
Gary
