I have an app where users submit new items and attach a file (only one can be submitted). The file name is then automatically added to a text field in PowerApps and the user can then select the submit button. Attachment is required in PowerApps.
PowerApps somehow loses the attachment in 1% of the submissions and I know the user attached it because the file name text field is filled out (value is anything before period so usually any text before file extension). However, when I look at the Sharepoint entry, there is no attachment.
I was able to replicate by submitting new items one after the other within seconds.
This also usually happens (not 100% of the time) when the file is big >2MB (there is a file size limit of 4MB).
Also, this happens more often when users use Internet Explorer.
Has anyone got a clue how to resolve this or is this a bug?
Things I have tried:
1. Upgrading PowerApps version.
2. Adding an 8 second timer before submission button appears.
3. Rebuilding the app using a template (Start from Data canvas app).
Please consider take a try to run your app using Chrome browser, then check if the issue is solved. Currently, there are still some issues or limits when you run your app in IE Browser due to Compatibility Issue.
Also please take a try to re-generated app based on your SP list data source, then run your published app within your Chrome, check if the issue still exists.
If the issue still exists, please consider take a try to submit an assisted support ticket through the following link:
