Indeed we are aware that we have issues with performance and we are working hard to identify ways to fix it. We released 15 days ago but it's a work in progress.
Giving it another try. Would be cool if you had a "saved layout" where I could just download a template that had all the apps I want to load up on new installations.
Are you sure it wasn't the apps you were running?
It could be linked to the apps being used (one clue is Whatsapp) but we are still investigating it.
