Would you invest large sums of money on Stashaway (or any roboadvisor)? Do you have a maximum amount you would trust them with?

I understand that our money is kept separate in a custodian account, but if anything happens our assets will have to be liquidated in order for our money to be returned to us (like Smartly). This is unfavourable if we're investing for long-term. Considering all the risks involved, do you invest large sums of money (say more than 50k) with Stashaway or a similar product? Is anyone's entire portfolio in Stashaway? Thanks in advance!
