MATLAB: Yyaxis change ylim for both axes

axesylim;yyaxis

I would like to change the ylim of the left yaxis. You can see that the ylim entry has no effect at all. I can only change the right side of the yyaxis plot. I appraciate your advice.
Best regards
%%figure
fig = figure (1);
set(fig, 'Units', 'normalized', 'Position', [0.2, 0.1, 0.5, 0.3]);
set(0,'defaulttextInterpreter','latex')
%%Plot data
%First subplot
ax1 = subplot(121)
x1 = linspace(1, 1000);
y11 = x1.^2;
y12 = x1;
yyaxis left
ylim([1, 100]); % Has no effect. Why?
plot(x1,y11,'LineWidth',1.5);
grid on
yyaxis right
plot(x1,y12,'LineWidth',1.5);
%Second subplot
ax2 = subplot(122);
plot(x1,exp(x1),'LineWidth',1.5);
grid on;
