Hello world,
Is a compatibility with kdrive (https://www.infomaniak.com/fr/kdrive/) could be considered ?
Thank you
kdrive offers a WebDAV interface, therefore it is already “integrated” 
You can read in our docs how to connect to WebDAV based cloud providers.
Can you please check, https://connect.drive.infomaniak.com/MyDrive/ is the URL to access your vault, right?
My credentials of kdrive are not valid on this url. I will check if there another ones to write.
My question is about the third services inthe android app, in Settings > Cloud services. There are a few services, is it possible to add others ?
Do you have 2FA enabled? If two-step authentication is activated, generate an application password here: Infomaniak
It’s a huge amount of effort to implement a new cloud connection (if they support it at all) with a lot of potential bugs that means if a cloud provider does support WebDAV there’s mainly no reason to not use the WebDAV connection. But we’ll better assist in setting up a WebDAV connection in the future: Assistance for WebDAV setup · Issue #192 · cryptomator/android · GitHub
Hello
