Why does a cloud account show "unavailable" in the Cloud Drive list?
Short answer: Storage Studio couldn't reach that account — offline, an expired sign-in or a provider problem — so it was skipped while the rest mounted. Run Test connection; if it passes, click Remount / Repair on the Cloud Drive tab.
Storage Studio couldn't reach that account when it built the drive — for example you're offline, the sign-in has expired, or the provider is having trouble. An unavailable account is skipped so the others still appear, and it comes back once it's reachable.
Check it on the Accounts tab with Test connection. If the test passes, click Remount / Repair on the Cloud Drive tab to rebuild the drive. If it fails, fix or re-add the account first.
