Wont Update – Goodnotes 6 Review

I bought this App and been really happy with it, I use it to take notes on my iPad every day and I can later review them in my laptop, iPad or iPhone; I can search the text I write, get pics in my notes, its a really cool app.... but then the updates started comming, it wont update all devices by itself, so if it updates itself on a device and the other is not updated, then it wont sync and I end up looking for files/notes like crazy until a realize there was an update, then I have to fish for versions and see which device is not updated. Looking for alternatives, maybe Notability.
