I am unable to make any changes everytime I connect a block the screen refreshes undoing the changes it’s very hard for me to do anything because the screens have a lot of blocks and it takes me a good 10-15 min lag and after that when it starts working I connect one block and it refreshes again and then lag again it’s very hard for me to do anything @domnhall can you check this out

This topic has come up frequently. Once you reach a certain number of blocks, things are going to slow down. You may need to optimize your code to reduce the number of blocks (e.g by using Any Component blocks). Or, it may be that your project is just very large/complex and can’t easily be optimized.
Regardless, I’d like to see a toggle switch in Thunkable that allows us to disable live previews while developing our apps. It’s rare that I need to see something change on a device _right_ after I change something in my code. It’s much more likely that I need to see the effects of a combination of changes (e.g. I might work for twenty minutes before needing to preview anything). But currently, making 50 changes means seeing 50 preview updates.

@farhanlatif027i3df This should probably get moved to the “slow blocks” thread. or any of the following really.

Exact 20 min for it to start my block screen then for every movement I do I have to wait 10 min additionally I wanna do so many creative things with my app but how can I when the lag is so so much I actually wanna cry when I realise I have to go back in blocks section to fix something I hate the lag so much

> I have a screen with a large number of blocks. The blocks execute fine on my device so everything is working great, but the Thunkable block editor on my PC is very laggy. Anytime I move or modify a block, there is a delay before I am able to move or modify the next block. When checking the javascript console, there are a very large number of errors “unable to find component with id null” that are being logged while the site is unresponsive. Is there any way for the Thunkable team to trace the s…
I was just at one of my worksites today where they have a google fiber connection. My project had near 0 lag. I am now at the local library and my block editor is lagging slightly. When I am at home, the lag is only slightly more than here at the library.
I really think that the lagginess we experience is a function of both the constant updating but also our individual internet connections. The better my internet connection, the less i feel the need to optimize blocks 😂 (but it’s still a good idea to optimize because i have to go home to my slow internet eventually)
I spent most of yesterday optimizing and was able to remove 400-500 redundant blocks through the use of FUnctions. One day, when the anycomponent blocks make sense, I feel I will be able to reduce the block usage even more!

It shouldn’t be moved there because my issue is not the lag but the screen that keeps refreshing

The screens I’m trying to access aren’t any new screens the screens im trying to access are the screens that I have been accessing for a long time it’s the sudden situation where I’m unable to access them properly even if I delete a block it refreshes

It could be part of the same issue. If not, keep it here. Seems though that if you are experienceing this issue during lag. You should figure out the source of your lag and get rid of this first. Then see if you still have this issue.
How fast is your internet connection?

currently i have a pretty laggy screen. up to 10 seconds at times I have to wait. But there are 922 blocks currently on one screen, at least 20 or more different variables in use across the app. and my connection speed is 44Mbps
earlier today my speed was over 100Mbps and there was nearly no lag

Sorry, I think I misread this initially. I thought your concern was that the live app keeps updating every time you make a small change. You’re saying it undoes your work. I have seen that before but only once or twice. Not sure about the cause!

That happened for me but it happened when I tried to change my label text or text input text.
