I have a GUI app that runs fine under MATLAB, however when compiled as standalone with MCC, I get a strange warning message
"warning: MATLAB connector is not running." when doing zooming my graphics.
There are very little info I can find on this warning. Can anyone help to point me to the possible cause.
Here is a screen shot of the command window:

Title
Why do I receive the warning "Warning: MATLAB Connector is not running" for my standalone application in MATLAB R2021a?
Question
For a custom application, the following warning messages appear in the command window, both within MATLAB environment as well as in the compiled application using MATLAB Compiler,

Why do I receive the warning "Warning: MATLAB Connector is not running" for my standalone application in MATLAB R2021a?
Answer
The issue was not reproducible in our side. However, adding the following line of code,
connector.ensureServiceOn;
before the call to function 'uiwait' the warning disappeared for the customer.
