Does not run on system startup

When I go to Settings and click “Run on system startup” it does not work. eMClient does not open automatically when the OS boots up.

Do you click ‘Apply’?

If you use Windows 10, do you see eM Client when you click on ‘Startup Apps’ in Windows Settings?

Yes, I click Apply.
Next time it happens I’ll click on Startup Apps and see if it’s there.
