Switch from wifi to cellular data
I will open an app, such as a podcast or online music in my house while connected to wifi. I go on my daily walk and about 5-10 minutes after leaving the house I lose the program. I push the forward button on the app and it does nothing but switch back to pause. I cannot restart the program by closing it and reopening it. The only way I can restart the program is by turning the phone off and then back on and restarting the app. I have my phone set to automatically switch between wifi and cellular data. Due to poor signal strength in my house I cannot connect directly to the cellular data to start the app prior to leaving my house. Is there something else I should try so that I don't lose the program and that the automatic switch from wifi to cellular takes place?
