Problem 723: QWERTY Shift Encoder

My following code works running Matlab 2024b for all test cases. However, 3 of 7 tests fail (#1, #4, & #5) the QWERTY Shift Encoder problem. Any ideas what I am missing?
Thanks in advance.
keyboardMap1 = {'qwertyuiop[;'; 'asdfghjkl;'; 'zxcvbnm,'};
keyboardMap2 = {'QWERTYUIOP{'; 'ASDFGHJKL:'; 'ZXCVBNM<'};
if length(s) == 0
se = s;
end
for i = 1:length(s)
if double(s(i)) >= 65 && s(i) <= 90
row = 1;
col = 1;
while ~strcmp(s(i), keyboardMap2{row}(col))
if col < length(keyboardMap2{row})
col = col + 1;
else
row = row + 1;
col = 1;
end
end
se(i) = keyboardMap2{row}(col + 1);
elseif double(s(i)) >= 97 && s(i) <= 122
row = 1;
col = 1;
while ~strcmp(s(i), keyboardMap1{row}(col))
if col < length(keyboardMap1{row})
col = col + 1;
else
row = row + 1;
col = 1;
end
end
se(i) = keyboardMap1{row}(col + 1);
else
se(i) = s(i);
end
% if ~(s(i) = 65 && s(i) <= 90) && ~(s(i) >= 97 && s(i) <= 122)
% se(i) = s(i);
% end
end

Sure, no problem. This following is directly from the Cody Problem statement:
Encode a string using the QWERTY shift code.
This code is where you touch type but are offset by one character to the right.
Only letters are encoded as the top row shifting does not occur.
(eg) "A" becomes "S" and "a" becomes "s"
"PpLlMm" becomes "{[:;<,"
An encoded message will never have any "QqAaZz" letters.
Illegal characters in the original message are "{{:;<,".
Encode "A-Za-z". All other characters are normal except for the Illegal characters.
Input:
str= "You miss"
Output:
encoded_str= "Upi ,odd"
