8 days passed. This problem could not be solved. There are 3 pending app updates but I’m holding them because of this error. I couldn’t figure it out no matter what I tried. I don’t want to create pages with the same blocks again. I want it to be known that I am impatiently waiting for it to be fixed. That’s why I want to keep the topic updated. Thank you for your understanding. ---

Is that correct? When was the last time you built an APK to test? We recently updated the build servers so it’s probably worth another try. What version of Android are you testing on? Is your Google Sheet shared publicly? I noticed in the sample you shared that all your screen names begin with emoji - have you tried to implement this on screens that don’t contain emoji in the names? ---

@doctorsof. I’m still a novice at creating apps but I have definitely put a lot of hours into the one I am currently making so forgive me if I am incorrect. I look over your app and I’ve noticed that there are two variables “x” and “itemID” that seem to have been created with a function or control block. Those control blocks or functions do not exist anymore. Try to initialize a new variable for those two. ---

Thunkable Live Test is not working. (Updated last version) So it is not important apk now for me. Web Test is working. It has not Google Sheet also. No emoji included now. ---

There are no blocks now. Is this project working well in Thunkable Live app in your phone? ---

I found why: Bug is from Text\_Input, I deleted all of text\_inputs it is working well. I added new Text\_Input that’s ok. But old ones must to be delete. I don’t know why but it is solution from old ones Text\_Inputs must to be delete and add new ones! ---

> [@doctorsof](#): > > I don’t know why but it is solution from old ones Text\_Inputs must to be delete and add new ones! Thanks for following up @doctorsof - just to close the loop on this, the engineering team informed me that with with the older text inputs, when you delete the text in the properties it defaults to `undefined` can causes an error. The bug was caught and fixed (which is why adding new text inputs work for you) but again, you only have to update the ones that say “undefined”. If they say “empty string” then they’re fine. ![txt_empty](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/c/4c874a93492b008e056505d845dcae4056fb7957.png) ![txt_undefined](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/d/dde6829334a457abcf7d9e1205d38584e84daca2.png) * * * > [@domhnallohanlon](#): > > It seems like there maybe two issues here Moving this to it’s own #solved topic since there were indeed 2 separate issues. ---
