The blocks area did not load properly. Changes to the blocks for screen 6271615010603008_Screen1 will not be saved

You don’t need the close screen block.

Seems like it worked after removing the Close Screen

Would you have any idea as to why a Video from Vimeo does not play on my second screen which is a part of my website which is being called in the webviewer… I can hear the audio i.e. sound of the Video that is being played but bo video… it is just a blank video…
BTW it does work when I open the site in the browser on my android phone but not working when I open the same from the simple Thunkable APP which has screen 1 in which a user accepts the user terms and on acceptance he is taken to the Screen2 (by the name DAS) which has a webviewer where I am calling my secured website (https:// …)

May be webviewer will not support it.
If not supporting in feature it will be available.
Can you send your blocks shot

Jerin Jacob

This is my Block Shot of Screen 1 and following is the designer area

Unfortunately looks like it is still throwing the same message… I guess I need to close the loop…
Below is my second Screen (by the name DAS) Designer shot …

If you open the webviewer URL in Google… I am able to open a link within my app to view a vimeo video, but it does not display if I am on this second screen of my APP and trying to open it from here…

You cannot recover the error messsage and if you still continue using the same with the error message you will loose the blocks after you have made changes. It is recommended to use a new project and start.

Are you sure about this??? I have already got my earlier APP published on Google Play… But it started showing this error after all this while…

Now when I need a version change it will be porblem…

Even if you create a checkpoint of the current app and as-well-as you export the .aia and reload. You will see the same error message.

Did you have an active internet connection?

Jerin Jacob

yes I do…

I made a copy of the one I had earlier… and it did not throw up the BLOCK error…
May be I would delete the earlier one and rename this to the earlier name or again make one with the same name to work at Google Play…
