Wow, sry to hear this! We haven’t had any other reports of this so far and are not sure offhand what could have happened. Could you answer a few questions to help us better understand:
1> What specific device model do you have?
2> What version of iOS?
3> What version of PocketEarth were you updating from?
4> Can you connect the device to your computer, and open iTunes. Then select the device, and choose the Apps tab. Then scroll down to the File Sharing section, and find and select PocketEarth. Does it show a file called “Recovery.pocketearth_archive”, and if so, what size does it say it is?
