Sometimes our Support team may need a little extra information to understand what’s happening in your browser. They might ask you to create a HAR file, which is just a record of the network activity in your browser while the issue is happening.
Don’t worry, it’s quick and easy to do! You just have to open a monitor tool in your browser, then replicate the issue. We have step by step guides below for each browser.
Note: HAR files can include sensitive details (like cookies or page content). Please share them only with Slido Support and keep them safe.
