When working with mask tracking in PrPro v. 23 when using tracking in a frame, its mode of operation fails every other time. There are times when tracking does not start and then does not work at all. There are times when tracking stops in the middle and that's it. You have to exit the program and log in again. And there is no chance that tracking will not collapse again. The most surprising thing is that if tracking is up at the time of its operation, then you cannot use the navigation buttons to re-work it. Screenshots are attached. This behavior with masks is also observed when there are effects on the clip. This is unacceptable for such an important tool.
