The inconsistent login signature of the old version of Altman Cosmos Hero is that the advertising plug-in is inserted into the software installed in your mobile phone, or the advertising plug-in is inserted into your updated version. Therefore, you will be prompted that a package with the same name with a signature conflict has been installed. Mostly because there is something wrong with the version you are updating, it was inserted into the advertisement. If you insist on updating this version, you can install a new version by uninstalling the original version, but all previous game progress will be lost.
