Hello Karen,
This is Jackson from the IMA SDK team to help with your issue. Tizen is considered outside full support for the IMA HTML5 SDK. This means that some features may not be fully tested on the device. See
this guide for more information.
I would recommend reaching out to your account representative for other options for ad support.
Please let me know if you have any additional questions.
Thank you,
Jackson
IMA SDK team
