I have Windows 10 and 2 iOS devices. I have E2EE enabled on Win10 to OneDrive per https://joplinapp.org/e2ee/. What is confusing in those instructions is step 5 never mentions enabling E2EE in the Joplin app on the subsequent devices.
When I go to the iOS devices I see a matching entry in the Encryption page and save the master key that I used on Windows10, yet I am always told via the orange bar on the iOS app to enter the encryption key. Why?
The notes come down from the Windows sync to OneDrive and are readable on the iOS devices… However, E2EE is not enabled on the iOS app. If I do enable encryption on iOS app I am forced to enter a password and even if I use the same password as the Windows password, it creates yet another key entry in the master key list.
I got so fed up with the iOS apps that I deleted them off both of the devices. I thought setting E2EE up would enable encryption from any of these 3 devices and they would use all the same key entry. I want to be able to create a new notebook on any device have its contents encrypted with the same key for all devices and be secure without having 3 different keys in the list plus a whole lot of empty keys from all my failed attempts to get this working
