Last week I figured i would try having a look again and suddenly the funds and tx history was there! I quickly sent my funds elsewhere and felt relieved.
The reason you did not see it before was because your wallet has not yet synchronized or fully synchronize with the blockchain, you will need to make sure you have good internet connection, and that the wallet has fully synchronized with the blockchain next time.
Now I'm trying to restore my father's wallet with a his seed phrase and am dealing with the same problem again, zero funds shown and no tx history
Make sure the wallet synchronize and have good internet. Hope your father did not extent his seed with passphrase? If the seed phrase is correct and not extended with extra words, you should see the fund. I will advice you to install mycelium on Android, or electrum preferably on computer, but can also be installed on Android too, import the seed phrase and check if the bitcoin appear.
