HBO Max recently updated their Android TV app so as to be unusable, imo. On an Android phone it is possible to install a previous version downloaded from apkmirror and the new app is detached from the Play Store and will never auto-update.
However, Android TV 10 (actually Chromecast with Google TV) appears to be automatically replacing the previous version with the latest version, regardless of where it comes from. Iow I cannot get the previous version to "stick."
Has anyone else noticed this or am I missing something? If I am right I don't think there is a solution. I am not going to change the package name with an apk editor.
I guess I'm lucky. I have auto updates turned on on my CCwGTV but my HBO max app is showing up as last updated 11/12/2021.
