Why am I being given suggestion to clear so many apps when updating my Gmail app is just 22MB? I've uninstalled up to three apps of more than 60MB but still can't update. I'm still not able to access my email on my phone even after updating it. Once I restarted my phone, I'd be seeing "getting your messages" but won't open. If I should "clear cache and data" on the app setting,which happens to be the only perceived solution, I hope my files won't wipe off completely?
