quality is off when posted to Instagram or Tiktok – Videoleap: AI Video Editor Review

I like all the features the pro comes with, but when I post the video as a Reel or a regular video to either IG or tiktok the quality is always bad! it looks fuzzy but in my phone gallery the original is better. Im exporting at 4k and 60 frames per second. Am I doing it wrong?
