I think it’s also worth bearing in mind the change in Monzo since the 2018 Ticketmaster stuff.
Are the time of June 2018, Monzo hadn’t yet hit 1 million users - and now we are somewhere over 7 million.
For one thing, the change in scale may make it not viable for Monzo to send out the same level of depth and detail as back then. Not sure what sorts of analysis they are doing nowadays, but I bet as they are spread over more financial products it’s not as easy any more to do those sorts of deep dives.
