J have tested this wallet before. Indio not like the wallet because it does not support seed phrase backup. The best you can do is to use the backup of the wallet to recover your coins. I mean the file backup.
You can wait for other people to respond, maybe they can give you a guide to how to recover the wallet using seed phrase.
I was able to get the correct seed ( 12 words) and I have tested using ian tool for BIP39 and it works and it shows the correct addresses for Legacy but not for the segwit (bc1q)
