Cookbook - Compatible phone apps

From my experience:

com.nextcloud_cookbook_flutter works really well
de.micmun.android.nextcloudcookbook cannot synchronize with the cloud it seems so has little interest
de.lukasneugebauer.nextcloudcookbook I didn't succeed in logging in with my murena account

If you confirm this problems, it could be nice to mention somewhere that the recommended apps is the first one to avoid the user testing all 3 of them for nothing.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
