When I am login to the app I can’t use the control buttons on Facebook (logout etc.)
When you’re referring to “app”, do you mean the facebook.com website? Which platform are you seeing this happen on? Windows 10? Linux? macOS? When the controls on Facebook stop working, is the rest of the browser still responsive?
If you notice the issue happening again and the controls under Facebook stop working, could you please paste the errors that you see in the developer tools via the “Console”. You can do this by using the following steps:
- When you reproduce the problem, open the developer tools using “OPTION + CMD + I” on macOS and “SHIFT + F8” on Windows
- Click on “Console” and either take a screenshot of all the errors or upload them as a text file
I’ll see if I can reproduce this locally in the meantime!
