Multiple upload fails if too much photos are added

hello i have created a form for my crews 

i have attach file selection , and google drive integration 

if in the forms my crews select too many photos i found out that the photos goes to google drive but the email with the details and also the submission do not upload 

thanks 

I assume that your uploaded files failed because of size limitations for the multiple file upload option.

The following note is quoted from this link below. 

Changing the Upload Size Limit

''NOTE: The multiple file upload does not support larger files (more than 100MB) yet. It would sometimes fail due to the resources it would take for the file to be uploaded. The single file upload, on the other hand, supports larger files.''

According to this note, I simply recommend you to use the single file upload for files larger than 100 MB or not to exceed the 100 MB limitation for the multiple file upload option.  

I hope this helps.
