Spell checker not working

Windows version.
Spelling errors are not underlined. I have selected the options in Corrections as directed in other posts to no avail.

CAn someone assist me… I have Eglish UK dictionary selected but have tried US and Canada.

Also worth checking in Options / appearance then Editor colours that Spell check underline is at default red, or whatever colour. It might have got changed so you cannot actually see the underlines.

Having this issue as well with Windows 1.9.16. 0. If you find a solution, please let me know!
