Some Skype for Windows users are experiencing a weird issue on Skype conversations. Users who are currently using Skype for Windows Version 184.108.40.206 may notice that some messages get displayed out of order. Thankfully, Microsoft acknowledged the issue and is currently working on fixing the issue.
This is unfortunately a known problem for some users of Skype for Windows with the very latest version 220.127.116.11 – As a temporary workaround while we are working on an updated version with a fix please download and install the previous version here: http://download.skype.com/msi/SkypeSetup_18.104.22.168.msi
If you are also facing this issue, you may need to roll back to the previous version of the app which might fix the issue. However, Microsoft may release a fix sometime soon, so you should probably just wait for the upcoming update.
