Can Tiller connect to JP Morgan Chase checking accounts under the Chase Access platform for business?
Welcome @arnoldsp1, 
If you can log in at Chase Online and access these accounts then you should just use the regular “Chase” search result when trying to add an account.
Otherwise, I’d recommend reaching out to our support team via the chat window in the lower right corner of the Console at https://sheets.tillerhq.com/auth/login and choose Send a message > Account connection issue > Issue adding an account > and then share the requested details with the bot to get it over to someone on the team to investigate further.
