Am I the only one where YT has gone to **** over the last few months? more often than not I'm getting weird stalls in the player even with good buffer health, weird buffer activity i.e. it will buffer way on ahead then suddenly drop back to 1-2 seconds ahead with the buffer length constantly flicking up and down, times where the video won't play beyond a certain point until I reload the page regardless of how much is buffered, instances where it glitches and just skips ahead ~10 seconds, etc. often reloading the page makes the problems go away on a particular video at least for awhile which suggests it is somewhat related to what server you are getting data from.
It is happening over all my devices and no matter what connection I'm on or whether I'm logged in or using private browsing, etc. etc. the only difference is what browser I use - Chrome tends to just momentarily flash up a corrupt frame and then continue, whereas Firefox has all the issues above and Edge if somewhere in between but usually closer to Chrome in behaviour. Need to remember to ask family if they are experiencing similar and/or if that happens for them when using my connection(s).
