My browser / operating system: iPhone iOS 13.4, all browsers

When I refer to “many devices”, I am talking about the vast majority of smartphones and tablets that have around 2GB of RAM. This term is subjective; obviously there are devices that are exceptions to what I state.

There are many issues with Scratch when it is loaded on a mobile browser.

Some projects do not even load on many devices – although (as of April 2020) this has improved greatly over the past several months.
When project do load and they are running, any lag will crash the entire webpage on many devices.

Additionally, if the screen is not wide enough, the project page will look like this:



One can see the (very obvious) blue margin on the right side that is caused by the stage not resizing.
However, that's not the only issue: many text elements don't load or don't load fully. That's a fully rendered thumbnail. The text doesn't appear once the project starts.

On a positive note, one can easily edit projects on many devices by turning the device sideways. Once the See Inside button is clicked, it is even possible to turn the device upright again.

Same issue with me.

I have a very similar issue with mobile, but i can't even get to the homepage before it starts loading

CNR, Scratch stopped responding when I attempted to control the project. Was using Chrome 71.0.3578.99 on EMUI 4.1 for Android 6.0.

Banana

Hi there, thanks for reporting these issues. Do you know if it is all projects, or just a specific project? If you could send links to some of the projects you are having issues with, that would help us work on this. Thanks

https://scratch.mit.edu/projects/200380992/ (this one doesn't even load on my laptop)

These two for sure are problems. I tried some other ones out, and they did load and function.
However, I have noticed that on my laptop (Windows NT 10.0, Firefox 64.0) these same projects have been freezing up my browser when saving or, occasionally, while running. (They weren't like this in 2.0 and no actual changes have been made to the projects since then.)

On a side note, the project page is broken on this device when it is held vertically. The page zooms in to about 125% at first. When zooming out, the page looks like this:

Based on some experimenting on my part it seems that the bigger the project is, the longer it takes/less chance of it loading. I have ones that are near the data limit and they won't load (website repeatedly crashes).
Don't work:

Works:

I recently heard that projects aren't working past 20 MB (which many of my projects are).

This is driving me crazy!!!
I am in safari and it keeps saying it crashed and it reloads to happen again

Actually, a friend of mine tried to load a project on iOS, and it didn't work. Then they tried on an Andriod phone and it loaded fine. Maybe this will be a clue here.

(Why do I always typo “Android”?)

Its possible older phone models (which will likely run old OS systems) might not load too well. Do you know which OS versions they are using?

I think it's a iOS bug. Even using the latest iPhone on iOS 12, some projects do not load for me (they usually cause the webpage to reload, but sometimes manage to load correctly). Some of these projects include https://scratch.mit.edu/projects/262564340/ and https://scratch.mit.edu/projects/292683919/

I have the same problem

But I use Android.

Actually my iPhone is old and has a glitchy battery percentage and it doesn't work on my iPhone. I was about to update one of my unshared project and it crashed.


OOF!

OMG same! I

I think it's a general Safari bug. If I use my phone or my Mac with Safari it'll still not work.

me too! I can't even colour stuff in! It always doesn't work and that really annoys me.
