After running into the problem numerous times of my latex getting changed to rich text format. I noticed a couple of repeatable and consistent causes.

For example if you have latex in your post and try to insert an image or hyperlink to another website this will more often than not cause the latex instructions to drop and the post entirety seems from my end to switch the post to RTF.

Do not know if this is repairable but I mention it for everyone's awareness.

The last switch occurred simply due to thread merge. The latex was placed in a separate post but the merge operation switched it to rtf.

This was what I had actually typed minus the latex command brackets.

Lol that activated without \[ command brackets on merge.

Both lines were using pmatrix latex format.

I have experienced this switch from LaTeX to RTF numerous times also - for me this happens when I simply press “Edit” after submitting a post that contains LaTeX.
