Don't trust this app!

It used to work fine - until today: woke up with my computer having crashed and suddenly NO session was shown in Session Boss to be recovered anymore. Not one from last night, not even a single one from the months and weeks before. I had about 150 tabs open for work and they are now ALL lost!!!!

PS: I cannot even save a new session anymore now, something seems to be completely broken with this plugin... (v 2.11.2)
