If I go to sainsbury and buy a few beers I will go and categorise the transaction as ‘entertainment’ as opposed to ‘groceries’. However the next time I go to sainsbury monzo puts my shopping into the entertainment tab unless I change it back - of course if I go and buy food this isn’t correct. What we need here is a second option when recategorisong which asks if you want to Recategorise it as a one off or change it’s default category
I get something similar at Sainsbury’s with petrol
️ I’m forever switching between groceries and transport.
I could see that with a large group like Co-op where they have pharmacies and opticians and travel agents. Go to buy petrol and groceries and the next time you go to their funeral directors it pops up as groceries 
Yeah I’m forever switching as well, I think lots of my old transactions are in-accurate as I only noticed this happened this week
Almost a year on and this still is my only annoyance with Monzo, still seems to be happening with the new current accounts too
