Arrangments are **gone**

well... this was not the first time that this happened. the arrangments were in the tablearrangment. but after trying to copy paste an arrangment it became horrizantal{which should be vertical and it still reports the same} and it just removed all of the arrangments... they still show they ''exist''
only the higlighted arrangmet shows up

and app inventor does not have undo which made this worse

need a reply ASAP please

Do not use a Table Arrangement, and especially do not try to copy arrangements/other components inside a table arrangement. It is buggy and will break things.

Just use vertical and horizontal arrangements to design your app layout.

ok but how do i return it now? app inventor doesn't have undo and i don't have backup

Yes, the table arrangement has issues...

Just use other arrangements instead... for example a vertical arrangement and 3 horizontal arrangements inside...


ok but the attached codes to the table arrangment is a lot. does it means i have to do the design and the codes all again?
