In the last couple of weeks whenever I have tried to use track changes in the Live editor, the behaviour has not been normal.
First of all, if I have TC turned on and Final view selected, as soon as I start editing a new segment it switches back to showing all changes instead of staying in Final view.
Secondly, in addition to this, it has now started showing deleted text as insertions (although if I turn Final back on, again, it is implementing the deletion correctly, it just shows as inserted tracked text instead of with strikethrough.
These are relatively minor but annoying issues as it disrupts the flow of working, and it's impossible to work in Final view which is most useful for avoiding introducing accidental errors with TC.
I'm using Chrome Version 107.0.5304.87.
