After that, when AI is trying to load the project, i have the following error:

When I load an old project, scrolling is possible again. But when I save this project under a new name scrolling is again NOT possible.

EDIT:

The components where i can not scroll are set as not visible.
When I mark them as visible i can scroll again, although I have checked "Display hidden components in Viewer"

Have you updated your companion app to 2.71/2.71u ?

Did you change anything in the project that displays this behaviour?

Hey Tim,

I do not work with the companion App, the Problem is in the Browser (Firefox, but also in Chrome)

I haven't changed anything since days

Can you create an example aia project that repeats this behaviour ?

From the Release notes:

The main body of MIT App Inventor now loads via the CloudFlare content delivery network. This should result in faster startup of MIT App Inventor.
Note: Sites with restrictive firewalls will need to unblock access to https://"".appinv.net (where the “” means any site name). This domain (appinv.net) is used exclusively to distribute the code of MIT App Inventor. Different host names are used for different versions.

Ok, thank you.

How can I unblock this?

Where is your computer?

At home?
At work?
At school?

What antivirus is installed?

What firewall?

What VPN?

At Home with BitDefender and no VPN

Have also tried to reach the site with my Android Tablet and still get this notification and can not display the hidden components

See here:

Screenshot 1 is the label visible

In screenshot 2 I have set the label to not visible and checked the checkbox for "Display Hidden components in viewer".

This does not work

What happens if you refresh the browser? The error persists?

12

Yes, also tried 4 different browsers now

EDIT: In AppInventor Offline Version everything is working

As requested, post the example aia project.

Working OK here, tested in designer with both Classic and Neo UI.

16

It is true that initially it doesn't show the hidden label, but once I refresh it, it works fine (tested in Edge).

Yes, same here

This time it worked, last time it does not

EDIT: This only worked in the small test project, for bigger projects refreshing does not work

18

worked straight away for me, no need to refresh...

19

Maybe something about refreshing the browser cache?

Either that or a restrictive national ISP?

20

Im in Germany, maybe @Anke can test it also?

Scrolling issue is there. For example, when I click on Extensions category, I have to manually scroll down to see extensions pallate.
