Not able to create a project on Nextcloud through Moneybuster (seems to try only anonymously)

Hello,

First, thank you for this very nice soft. I begin to use it a lot, and am very happy to have it open-sourced and available on F-Droid !

I have a Nextcloud instance with Cospend installed on it. I also have and android phone with Money Buster. When i try to create a new project on my server, i always have the "La connexion au serveur est coupée - Anonymous project creation not allowed on this server" error message, although i connected money buster to my nextcloud account, through the Nextcloud Files app, or directly with my credentials.

By the way, i'm not sure which value i have to put on the "email" field, on the project creation.

If i create a Cospend project on NC web interface, then any phone with money buster is able to connect the project with the ID/password or the QRCode.

The Nextcloud Files app is working correctly on my phone.

Tell me if i can give more informations :)
