4G faster than 5G

I've been using the 24ultra for around half a year now and I've noticed that my 4G is much faster than 5G for awhile now. Is it a common issue? Usually my 4G is at 3-4 bars but it's always faster than my full bar 5G.

Using speedtest, 5G is much faster, but practically using it for YT, browsing, reddit etc it is way slower than 4G. Takes a lot of time to load and sometimes YT vids won't even load properly.
