you can go fully non-custodial by setting up LNBits with Umbrel and using Blue Wallet on separate devices for each family member. However, that takes longer to set up, requires VPN connections for everyone, and seemed unnecessary for our casual game.
It's a shame, I feel you missed the opportunity to invest some time on something that, once is set up, it's more reliable and stay forever!
I cannot say it's more reliable, at least in my case. I had a setup where noncustodial wallet was a bank and players all had custodial wallets, so transactions between players were instant but bank to player took a second or 2 even if I had a direct channel to WoS. Also sometimes I had to restart my Tailscale as it simply won't connect. I can easily imagine doing a quick WoS installation on the friends phones to play with them, but setting up a vpn on each phone it's an overkill
