I use another service which allows me to specifically define, when they should do the sync of the accounts (also using Yodlee). I normally choose a period in the afternoon when I am awake and near my phone.

Since I get notifications for some services like my bank accounts, whenever there is a login, when it happens during the 15 minute window I specified, I am sure it is the service logging in. If it is at another time when I haven't manually logged in, then I know I need to be aware and maybe pay attention in case it is an attempt by a bad actor.

Ever since I switched to finwise, I am getting many notifications from my bank at odd times (especially since the finwise/yodlee implementation seems to fail often at syncing) based on the amounts of emails I get, so I am concerned that I no longer know if it is a legitimate login or a bad actor trying.

RFE:

2.Only sync during that time window. If a service fails to sync. Wait until the next window on the next day

I think this will also increase the reliability of syncing since everybody's accounts won't be syncing at the same time e.g. 5AM daily.
