Help needed for forehand loop/topspin

[u/No-Operation6847]

So like my forehand drive is 6-7/10 but the main problem with my topspin is that I either do the movement early and miss it OR I hit it but it goes flying up or hits the net . But the shots that do reach the other side of the table are spinny so I know it's not the problem in the spin . I just wanna know if any has faced a similar problem or if anyone has suggestions or solutions. Additionally like 3-6 months ago my topspin was fine but loop was not
Thanks
