Thanks for reaching out, Kristian.
To begin with, could you please tell me where you are trying to connect the Sintra Ai? Is it through the Sintra Ai or QuickBooks Solopreneur? Also, where is the prompt message coming from? This information will help us better understand the situation and guide you accordingly.
Please note that QuickBooks Solopreneur doesn’t have an option to connect with Sintra Ai.
Please feel free to comment below if you have any other questions.
