HUNDREDS of Vinted users are reporting problems with the reselling app.
Some users have complained on Twitter that they're unable to upload items or pictures.
More than 300 issues have been reported on Down Detector today.
One X user shared a screenshot of their Vinted app with an error message saying "something went wrong".
"Anyone know how to get past this problem on Vinted?" they asked.
Another user replied: "I think Vinted is down."
A different social media user said: "is the vinted app down or smt because why was i able to upload pictures a second ago and now suddenly it won’t upload anything because it keeps giving me an error that my pics aren’t loading or whatever."
Someone else wrote: "Why is vinted down and not letting me upload when it’s one of the easy tasks I can do?"
Most of the problems reported so far are with the app, although a small number of issues have also been recorded with the website.
Vinted is an online marketplace where users can buy and sell used clothing, shoes, accessories and other items.
It's similar to Depop, Etsy and Facebook Marketplace.
Set up back in 2008, it has now become one of the most popular online marketplaces.
The platform has 105 million users across more than 20 countries, including 16 million users in the UK.
Vinted users reported similar problems back in September, when thousands of users said the app was down.
