Tailwind effects on lift during a microburst

Hello guys ,

According to the principles of flight book i understood that only GS is affected by wind changes which is TAS corrected for wind, and the indicated airspeed remains constant .
According to the lift formula , lift is half density times TAS squared times S times Cl .

1: I know engine performance decreases with a tailwind , but how lift is lost during an approach with a high tailwind if my lift formula is not affected since my indicated airspeed is constant and everything else in the formula did not decrease ?

2 oes my indicated airspeed decrease in a tailwind or microburst and increase in a headwind or it stays constant ?

3: The book mentioned that airspeed dangerously drops during a micro burst so we try to compensate that drop with more pitch up and thus stall . What airspeed they are talking about ?

Thanks
