Hi all and ESRI Team!
I thought I was going crazy.. but I confirmed that 1.1 has no issues.
If I download a created App in 1.2 Developer Edition. Unzip it... do nothing to it... rezip. The Import either fails or spins endlessly.
I had made some changes to an already .zip file and tried to import which also failed, thinking it was something mis-configured, but I did nothing to a sample download zip as mentioned, still failed.
I then spun up version 1.1 and did the same simple test. download an app... Unzip, do nothing... rezip... Import ... worked.
Has anyone else had these issues or can confirm?
Have you checked the widget version? Please let me know if the issue still exists after you check the widget version.
I did this to solve this: first, remove the customized/outside widget from your web AppBuilder installation directory. Second, import the app file to the web appBuilder (develop edition). Its own widget will cover the 'hole' that you just removed. This should work. But next time, if you have another new app to import, you have to repeat the first step again.
