I asked this question recently while on the Mosaic line for an unrelated issue. Agent stated that it very frequently can take over two months for Paisly to post due to the manner in which Paisly and B6 interact regarding confirmed purchase. My Paisly related purchases from early October posted this week, so on target with your 45 days.
My tiles have been based on cumulative spend based on all purchases. This number can be seen within your TB account; "travel spend" and "card spend" as two separate items.
