Hi.
First of all I would like to make you aware that you most probably exposed your real name with the iPhone screenshot. If I am right you may want to modify this picture and mask it.
Bejond this:
The rename function in the mobile apps is rather basic and not really documented. If you rename a vault in the apps, you simply rename the vault folder. This means you are right, the vault folder is the name of the vault. Please be aware: if you change the vault folder name for a vault, all other devices that have this vault listed will not find the vault anymore, because the folder path (with the original folder name) does not exist anymore. You have to unlist the „old“ vault und add the renamed one so that the new vault path is configured.
Bejond this it seems like vault that were originally created by a mobile app cannot be renamed by a mobile app. I dont know why this is, but this is the behaviour on my environment with iPad/iOS/Desktop.
I recommend the following steps if you want to rename a vault (sorry, not very convenient)
- remove the vault from all devices. This will not delete the (encrypted) vault files. It will just unlist the vault from the apps.
- rename the vault folder directly online or in finder/explorer on your desktop app and wait until the sync to online is done.
- add the vault again to all devices.
Regarding the not visible vault name on your iPad.
Is there a change that you selected the vault folder as target of your WebDAV connection? If yes, please change the connection settings to the folder above your vault folder.
Please see here: "Vault is root folder of the cloud connection" dialog shown, what to do?
It’s tagged as android but it the same for iOS, but maybe there is no message in the iOS version. For me it’s worth a try.
