Good morning,
First of all, congratulations for your great program. 
I am using it for a while but I found some problems.
I'm running a project in HTML5, but I noticed that audio and some texts are not being played by Internet Explorer and Chrome Android, while I have no issues with Chrome and Firefox for Windows and even though I export it as an Android app.
Can anyone tell me why this is happening?
Thank you so much and I apologize for my english...
I use:
Windows 8.1
Internet Explorer 11
Tablet Huawei Android  7  -   Chrome  62.0.3202.84
Smartphone Sony Android  5.1.1  -   Chrome  62.0.3202.84
Smartphone Samsung Android  6.0.1  -   Chrome  62.0.3202.84
