Service Portal information messages are not shown long enough
The time limit set to display the messages is hardcoded
The time limit cannot be extended due to the code being hardcoded.
If you would like to be able to change the time limit, please submit an enhancement request so that the feature is considered for a future release. Note that several factors contribute to the overall prioritization of an enhancement request, even ones that we think are great ideas, and not all will necessarily become part of the product.
