If you are receiving an error message saying your seed words are invalid when attempting to sign into your wallet, it is important to take extra caution and read the pinned message in the chat. Scammers will often private message with fake names pretending to be admins, so it is important to never trust any private messages and especially never trust any links in private messages. All support should be done in public. Additionally, it is important to double-check the number of seed words you have recorded. If you are unsure of the number of seed words you have, double-check the instructions you followed when setting up the wallet and make sure the number of seed words you have recorded matches the instructions.
