Hello! The reason I’m wary of using a system reliant on cloud services is twofold, I guess. I’d rather handle my user data in the simplest way possible and insert it into my usual backup routine instead of adding a layer of complexity if it can be avoided. I’m also not a fan of staying authenticated system-wide to a cloud provider on my handset. I’ve done fine without a Google account on my Android phones up to now. I guess you can say I’m just conservative when it comes to IT.
I did notice the option of using recovery codes for some services, although Twitter doesn’t seem to offer them.
Regarding the update, my Android (v10) package manager is showing me nothing more than a terse “Installation Failed” message, which is shown extremely quickly after the installation process begins. Less than a third of a second after pressing “install”, immediately after the archive is extracted to some buffer somewhere. This started happening with the v3.34 release, and is still occurring today with v3.35.1 (335101). The Duo Mobile app had previously been updated successfully in the past on this handset, a couple of times, I believe. I’ve tried restarting the phone and clearing the cache for this app, to no avail. Thank you for your offer to assist me with this issue.
