Hello all
( TB 3.0.1 + Google Agenda 6.01b )
All was perfect until ... I have to reinstall TB.
In my TB Agenda I had only the names of my agendas and the links were bad.
Now I have no more events on my google agendas.
What means for this extension the term 'bi-directionnal"
Is it possible I deleted the events in google during syncronization ?
If yes, is there a solution to recovery the google agendas ?
Thanks
