Hello! The old version of the cast panel was installed on the phone and I accidentally deleted it. I have not been able to update the panel for a long time because the cast is no longer supported on phones. Now I am completely left without a panel on the phone !!! It is impossible to bypass the restrictions of the Android system on installation from unknown sources. Developers, what is the problem with giving users the opportunity to decide for themselves whether to use the panel or not ??? I specially repaired the old Redmi Note 8T for use as a stationary panel. On the new Roko M6 Pro phone, the latest version of the cast panel was installed without problems. What is the problem ??? Please return support for all phone models, it is not difficult !!!
