Hi @yanngagnon, thanks letting us know and glad you figure the solution. Indeed you will need to stop tracking in this instance and be careful of the order but I will pass along your comments to developers who may be able to provide you with an alternative if appropriate.
May I ask specifically what flavour of the Tobii Core SDK you are running? I think it would be great if you could share some of your project when possible for any other users interested in MVVM Architecture.
