Resolving Chromecast-Hoopla Inter-operability Problem

I am describing below a Chromecast-Hoopla inter-operability problem & its resolution.

Description:

I noticed the problem first in October of 2024.  I would cast to Hoopla via Chromecast from my Android phone.  The TV screen showed the movie being loaded (the circling Wait icon) and then it would stop and would only display the blue Hoopla screen.

I verified the same behavior with Apple iPhone.

The specifications were:

• Device brand and model: iPhone 14
• Operating system, found in device settings: iOS 17.61
• hoopla app version: 4.60
• Chromecast model: firmware – 1.36.157768

and

• Device brand and model: Galaxy S8
• Operating system, found in device settings: Android 9.0 
• hoopla app version: 4.77.1
• Chromecast model: firmware – 1.36.157768

and

• TV: Sanyo
• Model No.: DP32242 HDMI
• Manufacturing Date: SEPTEMBER 2012

All devices were on a home wireless network.

Resolution:

I could not update the firmware on the Chromecast since there was no option to do so using Google Home app. on the Android phone.

I updated the firmware of the TV set from the Web (it was on the wireless network) via its remote-control options.

The Chromecast-Hoopla inter-operability problem was resolved.
