This morning I went into market and saw that 4 apps needed updating, 2 of the apps were on my SD card. The 2 apps not on SD updated fine but the 2 on SD card forced Marketplace to FC. When I went back into Market the apps were in the process of updating and seemed to update and run. However after rebooting the phone the apps were no longer installed. It was at this point that I noticed Market had been upgraded to 2.12. I tried installing the apps again, which succeeded but when I tried moving them to SD card it failed. I had to uninstall/reinstall the apps again and I was then allowed to copy them to the SD card. I have now done a clear data and clear cache on market to see if that helps. All my other apps are fine both on and off the SD card and I used to be able to update them on SD card with no problems. Until I get another update for an app on SD I cannot be sure the problem is resolved but it does appear that 2.12 managed to break something. Anyone else had similar issues?
