Was looking through some old transactions from last year ad Uber has changed from Transport to Eating Out for the months of May 16 to July 16, has this happened to anyone else?
Has been reported to support via chat but it shows as Transport on Mondo side?
If you take a look at an Uber transaction via the API, youâll see that the default for that merchant is Transport.
But if you change a merchantâs category (when you order from Uber Eats & the transactions are grouped under Monzo [which does need fixing], for example), Monzo remembers what youâve changed it to & applies that category to all future transactions, until you change it back. Iâm guessing that, thatâs what youâve done here.
Nope, UberEats is not round here and as it has always been transport Iâve never touched it. It was transport previously though, also not used them since October when they blocked my card so had to go back to MetroBank card.
Unfortunately I donât have any Uber transactions before August last year but if you check yours via the API & the category is âtransportâ (make sure that youâre looking at the Merchantâs category, not the Attachmentâs category), then youâll know that the category wasnât changed by MonzoâŚ
I expect youâll see that the Attachmentâs category - which is the one that the user controls - is âeating outâ. In which case, if you havenât changed it, then either the support team or someone with access to your account must have.
If Iâm right, it should look something like this -
I donât know how to work the API but I changed them all back now anyway, just wondered if anyone else had seen this happen.
You can still check those transactions because when you changed the category for them, youâll have changed the Attachments category not the Merchantâs category (which is the one that Monzo sets). If the Merchantâs category is âtransportâ then it was you who changed the transactionâs categories.
Itâs surprisingly simple to use the API:
then youâll see all of the transaction details, including the information in my above screenshot.
Nope both are transport
In that case you had changed the category 
(this is why the Attachmentâs category is no longer âeating outâ)
But if I changed it then why would say 20 only change and the rest remain as Transport?
Because you spotted the incorrect category & changed it back to Transport.
I meant that between May - July they had changed to eating out but from July to October no changes had taken place.
I had to manually change every single one from Eating Out to Transport in the earlier date range
Yeah so Iâm guessing you chose Eating Out for an Uber transaction in May, then chose Transport for another one in July. As I mentioned, Monzo remembers which category you last selected for a merchant & applies that category to all subsequent transactions.
Nope I know I didnât change anything also you said
So surely they would all be eating out?
You have a much better memory than me then 
Changing a single transactionâs category doesnât update all / any of the categories for a merchantâs transactions. But Monzo remembers what category youâve just assigned to the merchantâs category & applies it to all new transactions thatâre made after you make the change.
lol I dunno mate, I know I randomly go back and look at transactions to see if they are all in order and spotted this.
I guess itâs going to be one of lifeâs little mysteriesâŚ
