Up until sometime last year, there was no limit on how many hashtags you could put into TikTok posts, to which point you can include stuff to do with almost everything in the said post. For some reason however that’s been changed to point where each post can now only have up to 5 hashtags, this does not seem very ideal and things should go back to having unlimited hashtags like things had always been prior to last year, same I say in regards to other social media sites that started limiting how many hashtags there can be. It’s a pity though that you won’t be able to edit the descriptions of those posts with only 5 hashtags, since you only have until 7 days after posting to edit them. But maybe that’s something else that should be changed sometime, of which can even help a tonne with those posts where we might not have the right sort of thumbnail and taggings for.
