This is something we’ve been investigating since the app’s inception and we continue to investigate constantly. Syncing is a very difficult problem to solve, especially in regards to handwritten notes which can be combined with images and text. I don’t have any kind of ETA for when syncing will be supported, but rest assured this is a high priority for us. We appreciate all your feedback on this idea.Gustaf commented
Being a paying and avid long time user of this app it's very disappointing to deduct that there really can't be any development going on. The last update was over a year ago without giving any hint as to progress or expected completion. As sad as I am to admit it I am now actively looking for alternatives to squid. I would even go as far as suggesting this thread moves on to finding that alternative since everyone here wants the same functionality. I'm leaning towards OneNote but am not keen on the lack of drawing/ writing options. Has anyone else managed to find a better option including sync?
