I could have sworn I had backed up Weatherbug. I hadn't. I do not like the newest updated version. I wondered if there may be a source that lists all versions and would also have the previous version .apk that I could download and reinstall until they get an update that I prefer. Thanks for any help or suggestions. on edit- I have always connected my MAXX to my computer, highlighted all folders and copied them to my PC. In the past, I had and app_backup file that contained all my .apk files. I could not locate such a file, now. Not sure why. But, maybe simply dragging all folders from my phone apparently, for some reason, does not include my .apk files, but not sure why.
