eSupport Portal Switching Languages
Something is causing the eSupport portal to unexpectedly switch from English to Chinese. It's definitely tied to cookies, but I can't figure out what is causing it. I'm using Firefox as my primary web browser with Windows 10. I use the support site extensively almost every day and suddenly out of the blue it will switch the language to Chinese. I do not have Chinese configured as a language in my web browser nor is it an installed language in Windows. Every time this happens I delete all cookies for ptc.com and that resolves the issue for the time being, but not permanently. Not sure how to troubleshoot this, but I really wish it would stop happening.
Not sure if it matters, but I use https://help.ptc.com frequently because it's easy to remember. I wonder if something is messed up with the automatic redirection from there to https://www.ptc.com/en/support/help, or most recently https://www.ptc.com/cn/support/help.
Here are the last three tabs I opened. Notice the transition:
