Yes, sounds like you are going past where you are able to hold position.
You don’t want to keep going past this point as it can develop bad habits.

It may be different from what you have done in the past. Creating the awareness of where you lose tension within the range of motion is a first key. This will illustrate where to mobilize/point of restriction.
I recommend Carl Paoli’s Freestyle Move Strong I Squat Progression on the Cody app.
Great progression to rebuild technique.
