Steps to Reproduce:

But for vanillaJS, the intelisense still works

Does this issue occur when all extensions are disabled?: Yes/No
YES :/
I have the same problem. After the last update it stopped working.
Same here. Language is set to Javascript React and still not autocompleting/listing JSX attributes as it was before.
Please check the TypeScript Server trace:
"typescript.tsserver.trace": "verbose"TypeScript sectionAre there any errors or stack traces printed near the end?
Unfortunately I did saw a stack trace printed, but decided to clear it in order to see if it was still happening, but it turns out that it isn't.
No stack traces or errors are being logged on Typescript, however the issues still remains.
Let's hope that the OP is getting something in the logs.
For me, it automagically back to normal
Sorry for dont help @danfsd
No problem @yuritoledo, it's back to normal for me as well. I think it went back after the 1.28.1 update. Try updating to that version @jmsstudio.
I think the issue can be closed @mjbvz
The problem still occurs on my VS Code...
I updated my version but it didn't change anything regarding this issue
@jmsstudio it works with normal JSX button / input too?
I disabled all the extensions and tried again, it worked now
Sorry for the inconvenient, it was some extension trouble here
Now the only problem that is still occurring is related to import not being placed in the file header with the imports, but it is another issue...
@jmsstudio great!
