When installing Mycelium, the first time it asks whether to start a new wallet or restore a previous backup.
However, once a new wallet is running, is it still possible to import a HD backup (12 words) from another wallet? Or better yet, (temporarily) switch to a different HD wallet, by entering 12 words?
The problem is: I recently installed Mycelium on my phone, started a new HD wallet, but now I suddenly doubt if my old wallet still had some bitcoins left. I still have the 12 words (for both the old wallet, and the new one). But I can't seem to open or restore or import an old wallet anymore, once a new HD wallet has been created??
I was going to post "no problem", but now I'm not so sure. Mycelium seems ready to manage many accounts in parallel (see "accounts" tab, where you can select the active one and manage them).
Unfortunately "add hd account" will not allow import of a HD seed, but only allows creation of new "HD accounts" using "your seed". This seems to imply mycelium can only handle a signle HD seed. (note the problematic use of the term "account" in mycelium to mean different things like "wallet" or "hd account").
On the other hand: under the "add account" icon (a key symbol with a + sign) -> "advanced" -> "scan" one can supposedly add "unrelated accounts", including HD accounts. It doesn't seem to allow entering of a seed, only to scan qr code (which I wouldn't know how to encode a hd seed into and frankly wouldn't want to do it for security reasons)
So: I'm not sure.
