However, Google’s approval process can take 3–5 days and is outside my control. This is a free tool that I maintain in my own time, and I do my best to keep it reliable for everyone. If you prefer to use a different extension in the meantime, that’s completely understandable — you should use whatever works best for you. That said, I would ask you to keep in mind that reviews have a lasting impact, while bugs are usually temporary and already in the process of being fixed.
