You can connect PayPal to use as part of the Wealth Tracker product in our app. However, Plaid does not currently allow you to transact with a PayPal account once it's connected, and this means that PayPal cannot be used as a funding source for your portfolios. This ability to transact is something that would need to be updated between PayPal and Plaid, unfortunately it is not something Allio can control.
Most major banks do support moving money via Plaid, so you should be able to connect another bank account through Plaid to use as your funding source with Allio.
