Have you been living under a rock of something? 5 sat/vB transactions haven't been clearing since April, let alone 24 hours. The lowest fees clearing in the past month appears to be around 12 sat/vB right now.
Overall though fees have continued to decline over the past week or so, depsite all the "doom and gloomers" claiming that the fees would never come down again. Clearly they've never heard of altseasons, which are short lived, and this time involved BRC20 memecoins and as well as Ordinals inscriptions. It seems quite obvious that these short-lived fads have passed for now and fees will continue to decline.
If previous mempool history is anything to go by, then once the 10-12 sat/vB transactions are cleared out, the rest should clear out pretty quickly after that.
