Please see the error below. Could someone please suggest what could be the issue?
**Something went wrong when we tried to build your project** **CancerCare** \*\*.\*\*

Is this the first time you try to generate an APK for this project?
Is this a project copied from an earlier project which was APK generated?

This is strange. Sorry it’s happening and thanks for bringing it up.
Is this occurring for all users and all projects today?

I am getting this as well, however when I tried downloading for ISO it seems to work fine. 🥺
I have downloaded it once before maybe I late Jan2022. Fixed some issue this week and now I get this issue while trying to download for Android

Strange… It is working now!!! Thanks. 🤪
However the installed app does not display properly, seems like many pieces are missing 😵
Android:
Block functions are mostly there but images were all lost

You using images as assets in the project. It seems you changed the assets name and made it different from the actual file name.
If you do this, the compiled app will not load the images.

I notice the shadows. We’re working on the fix and hopefully testing it this week.
Where do your icons come from / what file format are they?
Lastly, how are your elements ordered in the tree. If you don’t mind it does seem a bit strange, if you want you can DM me a link to the app and when I’m at my desk I’ll take a look!

Thanks @muneer @jared for the help and solution.
I imported most background images and setup from Figma, I added the icons after that, they are .svg
Heres the link to my little app that im working on at the moment:

Anyway! I am still enjoying Thunkable and the building process 🤩 and of course the immense help from the community!! 🤩

This is what I see. squished by the white. bar at the bottom, b ut everything is there. this was taken on an android device.
Can you make sure you are on the latest version of the companion app?
[UPDATE] when i downloaded the app, the assets were not present.
I have pinged the team and will follow up here when i have more details.

This (bug) **unexpected behavior** is only present in Android in the APK. iOS is not effected.
This is why the same project will compile correctly in iOS.
