I can't help but think about a closed source wallet like Trust wallet, I think that's what you used because I'm sure it does prompt you to storing your seed on a google drive while creatinga new wallet ..if I'm right, move your funds to a moresecured open source wallet like Electrum, unstoppable, Blue wallet..
Also I believe, you meant a paper notebook and not a digital notebook on your device,if not then do it right... lastly, test it by importing it on a new wallet and keep multiple backups of it.
Two risks here
A close source wallet.
A command or suggestion to require users backing up wallets on Google Drive. It's less likely the case with any wallet but if any wallet asks users doing this step, it's very dangerous and you should migrate your coins to a new wallet brand as soon as possible.
A close source wallet is not recommended for using because it's irreproducible and it's hard for users and community to check and test whether there are backdoors in the wallet code.
Trust wallet is close source, if you wonder whether it is not close source, this wallet review confirms it for you.
