Common help

Restore Host Plus

Open the Premium screen and tap Restore Purchases. Make sure you are signed in to the same Apple ID that bought the subscription.

Cannot join a room

The host's app must be open and the host must be online. Codes work only while the room exists; closed sessions return "room not found".

QR scanner does not work

Allow camera access in Settings → LetterBlitz, or just type the 6-character code by hand.

I lost connection mid-round

Reopen the app — you will rejoin the same room automatically. Answers typed before the disconnect are preserved.

Premium did not unlock

Tap Restore Purchases. If still inactive, send us a screenshot of your Apple receipt by email.

Data deletion

Email us with subject LetterBlitz data deletion and the device identifier from the in-app premium screen.
