On Windows, using two premium users, at the same time, anyone of the instances crashes at any random time, It is becoming more and more frequent to my recall it is only happening in the last version (6.19.2.8555 (308555) Public (CE Build ce-62.3.7750)), sometimes I don't see one of the instances crash because it just vanishes, so I go to the other one and try to open the missing one again and can't because it tells me that it's already open, so I close the working instance.... but Clipper and Tray app don't close and they have to be ended with task manager, only then can I open again both instances.... and wait for the next crash.... seriously considering downgrading until this gets fixed... I have observed at least one note became damaged (Lost content)
