Delete older APK copies from the downloads folder, restart the browser and download once from the confirmed route. Multiple similarly named files can cause the wrong version to install.

Clear app cache only when needed, then review install permission for the browser. Avoid installing files sent through chats or mirror pages.
After updating, test login before opening wallet pages. If login loops, move to the help center instead of repeatedly installing new files.
