It wasn't necessary to update
Yes, after the so called update to remove ads, which is useless, and not necessary, this app became unstable and crashes every now and then. I don't recommend to update the app since it has a cost. But the app is free! Besides I hate the $ sign on the top bar. It is also a pain in the neck to either look for information or some word, or the keyboard doesn't react fastly, it becomes "sticky".
