Saw announcement for 4.3 upgrade - composer update not upgrading it to 4.3 but still on 4.2

I was able to fix it but it only a workaround and they are still discussing on best a solution to this. The workaround is on slack channel link below.

Check this slack thread - Slack

I did the workaround steps show in slack and I was able to successfully upgrade to 4.3.1 but back up fully first and keep in mind it’s not an official fix however so far it’s working for me.
