When Apple and Google update their Operating Systems developers sometimes need to update their apps too. I don’t know all the technical aspects but sometimes there are changes in the OS that mean the developer has to account for new or changed capabilities or functionalities of the OS. Usually this is the sole responsibility of the developer. But as apps are made using Thunkable it _may_ be the case that some background changes need to be made in the way apps are compiled. The developers of Thunkable should look into whether there are indeed changes required to how apps are compiled. ---

> [@Dean\_Artis](#): > > it _may_ be the case that some background changes need to be made in the way apps are compiled. Thanks @Dean_Artis - I’m fully assuming this _is_ a change needed on our build servers. We have just rolled out some infrastructure updates recently so just trying to establish from @tony.ycy.program and @doctorsof if these are apps built today/yesterday or if they were built prior to that? Can anyone else on iOS 15 chime in here? (I’m living in the dark ages back on 14.3 😂) ---

Just tested 2 of my apps on ios 15, both compiled and published earlier this year and both working fine without the update notification. ---

> [@martint](#): > > , both compiled and published earlier this year How much earlier @martint? I think iOS 15 only came out yesterday? Now that you mention it, were either of you on the iOS 15 beta @doctorsof or @tony.ycy.program ? ---

I didn’t use ios 15 beta. I updated yesterday to ios 15.0 right. I wish I had waited a couple of days. ---

> [@martint](#): > > Both last compiled and published pre July. Interesting - ok, well that’s good to know (this is the Funhall app, right?) Just by way of letting you know what I know so far, it looks like we might need to update the software on the machines that build our iOS apps and it should be possible to get that done within the next day or so. I will keep you all updated on progress (and probably check back in to ask for help testing when the update goes out) but in the meantime please point anyone with a similar issue in the direction of this thread. Thanks! ---
