    Still totally broken for us in 2023.9. Tried .11 but still the same. Rollbacked to .5, everything's working fine. There is definitively more stuff with this issue, not everything is fixed.

    Was getting this in 2021.3.8, it does indeed seem to be resolved in 2021.3.9.

    Just spent 3 hours making video and uploading my entire project for bug reporting twice, because of this bug. And I didn't know it was already being addressed. It is hard to find such duplicate case in the jungle of issuetracker so if something like this major critical bug exist, it should be pinned at the top of the relevant forum site on Unity ( UGUI&TextMeshPro) So......... Frustrating!
