It is extremely buggy. I have a friend who works in video ending and is always sending me screenshots of how Premiere has tortured him today. Also recently saw a social media post of someone complaining how adding 5 PNG files to his project crashed Premiere, but not after auto-saving the project with the PNG files in it, essentially destroying the project.
Both Adobe Premiere and Adobe After Effects are buggy, unreasonably slow and very, VERY quirky pieces of software. I switched to Davinci Resolve a few years ago and my work output skyrocketed almost overnight, but while the performance it offers is something adobe engineers can only dream of, it still lacks certain features some pros need, so they remain trapped in the adobe/avid gulags.
