Thanks for help!
I found version 2.8.0 and got it working. My Android version is lower than 10, so it should be fine. However, I read online that version 2.8.0 has some issues with EPG updates. Users reported that after a certain number of days, they couldn't update EPG data regardless of what they tried, until they reinstalled the app. Is this true?
Regarding Tivimate app versions above 2.8.0, I noticed from this forum that even if all license servers are blocked, the app may lose its premium features within a maximum of 15 days because it cannot contact the license server. If this is true, and if the Tivimate developers stop development and shut down their servers, all legally purchased apps could lose their premium features within 15 days. This would be unfair to those who paid for the app, especially since the license is supposed to be for a lifetime.
Is there any Android app which is very similar to Tivimate and which is hacked completely?
