Update 18 introduced a different workflow where the "Request Payment" option is no longer available in the subaccounts, only on the Home screen. The automatically selected subaccount changes with every (outgoing) payment which has nothing in common with my payment requests (incoming) and is also not sticky to the last selected option. Even worse, if you have multiple profiles (e.g. personal and multiple businesses) it even skips between the different subaccounts between profiles. I've made several errors in requesting payments because of this mixing personal money with business money. Receiving payments from my friends for our fridaynight drinks on my business payroll account creates quite some noise in my bookkeeping.

Option 1: rollback the UI change so that creating a payment request in a specific subaccounts that makes the payment request specific to that subaccount.

Option 2: change the UI so that the last chosen subaccount in a Payment request is sticky and not dependent on the last outgoing transaction.

Option 3: introduce a setting to choose a default payment request subaccount somewhere in your profile.

For people with multiple profiles or regular changing subaccounts for Payment request, option 1 is the best because choosing the account where you want to receive is embedded in your workflow automatically. Option 2 and 3 still need extra attention when creating the Payment request because the option is "pre"selected and not an active choice in the workflow (thus higher error rate).
