Keep training. Just work in the ranges you can control and work farther as you improve range. For example, squat as deep as you can during training while maintaining control and sprinkle in 1 or 2 hip mobility drills between sets, during warm up or after wards and keep exposing yourself to the improved ranges. There is no reason to stop training though it may take you a few months to get to where you want to be. Improving mobility while continuing to train is actually how it works best.
