Trim tool malfunction

Version 1.57 Samsung S7 + tablet

Trim tool suddenly began malfunctioning. I can no longer trim symmetrically. If I start a new file, it works properly again.

Please make a video or screenshot.

First example is an older project I had saved. The second is a new project.

I don’t think there is any bug, please check your symmetry plane, it’s likely off.
Maybe set it to Local, or recenter your mesh but I can’t say much without having the file/object.

Yes that was the problem. Thank you
