Performance Slowdown After Updating to Thunkable Live v530

Questions about Thunkable Issues / Bugs

Hi Thunkable Team,

I wanted to report a performance issue that started immediately after updating to the latest Thunkable Live app (v530).

Since the update, all of my apps have experienced a noticeable slowdown - particularly with screen transitions. Previously, transitions were almost instant, but now its not uncommon for transitions to take 1-2 seconds to load. This happens across multiple projects, including ones that were running smoothly before the update.

I’ve tested this on the same device, with no other changes besides the Thunkable Live version. The slowdown appears to be directly tied to v530.

Could the team please look into this? Smooth screen transitions are critical to the user experience, and this regression is pretty significant.

Happy to provide more details or run tests if needed.
Thanks!

Hi @grant.mccallum
We can understand that it is frustrating and appreciate you taking the time to investigate and provide more information.

We have flagged it to our engineering team and will provide an update as soon as possible.

Thank you, again, for your time and patience in this matter.

Hi @ioannis,

Thanks for getting back to me.

I can now confirm that this slowdown is not limited to the Thunkable Live preview. It is also affecting exported APK builds. I have a recorded video showing the exact same project, with zero code or design changes, loading in one second in an APK exported two weeks ago and taking roughly ten seconds in an APK exported today. I can share this privately if needed, as the app belongs to a client and I cannot post the footage publicly due to NDA restrictions.

Short version:
Previous APK load time: 1 second
Current APK load time: 10 seconds

No changes were made to the project between these two builds.

This strongly suggests that something in the recent runtime or build pipeline has caused a performance regression. Please escalate this to engineering as an urgent issue, because it directly affects production apps and client deliveries.

Happy to provide any additional information you need.

Thanks,
Grant

We need answers please. It’s been almost 24 hours since this problem occurred and it has completely stopped us from being able to work. This is urgent.

Still cannot work. Whats the outcome here?

Hi @ioannis

Just checking in again as there’s been no update yet. This slowdown issue has now been affecting multiple developers and clients for over 72 hours, and it’s completely halted active projects for us.

I have been unable to test, publish updates, or deliver builds to clients until this is resolved, so it would be really helpful to get a status update from engineering, even if it’s just confirmation that the cause has been identified or an ETA on the fix.

Thanks,
Grant

Hello,
Our engineers are looking for the root cause, so we don’t have any timeline for a fix yet.

We will provide an update as soon as possible.

We appreciate your patience on this.

Hi @ioannis

We’re now on Day 5 of this slowdown issue, and we still haven’t received an update from engineering. This regression continues to block active client work, testing, and publishing. At this point I’m having to delay paid project deadlines, which isn’t sustainable.

Can we please get a clear status update, whether the issue has been identified, what the current fix progress is, and whether you have an estimated timeframe? Even a brief technical summary from engineering would go a long way.

This is a critical production-impacting issue for several of us, and I need visibility so I can plan client work accordingly.

Thanks,
Grant
