Today I had the job to choose a certain type of DELL computer and then send the link to a colleague via Mattermost PC client.
He told me that a configuration window opened instead of the chosen product.
After a while we found out that Mattermost adds a “|” to the end of the URL, encoded as %7C. This makes the parameters invalid and so the main configuration screen is shown by the web site.
Server version: 5.21.0
Client version: 4.4.2
Why does this happen?
