Thank you for the reply. Interestingly, I thought the cause of this reloading is because of non-downloadable notebooks, and I subscribed to premium only attempting to fix this by enabling the offline mode (although failed xd). From my limited knowledge, I guess the cause could be some synchronization implementation, which Apple's Notes does very well. I hope Evernote tech team can see this and make some improvement. This sabotages the user experience a lot especially for cases like this, Evernote is well known for its simplicity and easy to use, but if this problem on IOS persists, it is actually better to just use Apple's most basic Notes app.
When viewing notes on the phone, frequently I switch to other apps to do things like reply message, searching some content of the notes on the internet and so on. However, unlike the built-in Notes app on IOS, Evernote frequently reloads itself and returns to the top of the page and unsaves the action performed before switching to other apps. It very frustrating when the note is very long with lots of tables and we are editing something. It would be so much easier if the app can keep its status in memory much longer so that we can view the same things again after switching back. Since IOS Notes itself can do it and there is no problem on my Mac, I assume there could be a way of fixing this for IOS? I am using a iPhone 8 for reference. Thank you very much.
