thanks bro for your reply but somehow it doesnโt work for me, even when selecting the tier 2 from extension pop up and refresh, the page still doesnโt show the offer plan card page, it only shows the subscription management page.
Bro check the Google AI Pro 12 months trial, you are looking at youtube premium price you are good to go, just go ahead and subscribed, and than cancel
oh ok brother tysm again 
youโre welcome and bro can you try and tell me if the tier 2 option working for you or not, check how to do it by @kimambo_jr above
try tier 1 again
i think tier 2 isnt working 
for me
yeah bro same for me 
ooh
