use IQ applications without having to stop the activity

I am having the following problem, when I want to use the IQ of wikiloc or trailforks I cannot enter unless I stop and save my activity in progress.
I can't find an explanation, I want to be able to load IQ of wikiloc route or load my list of trailsforks and be able to follow them without having to stop my activity. Because it happens? Is there any way to fix it? in the negative case, can you propose this change in future updates?
