We would like to check if anyone else in the community is experiencing a similar issue when uploading large video files.
Previously, in our applications, we were able to upload .mp4 files of up to ~400MB using a File-type column without major issues (only expected delays or occasional timeouts during upload).
However, recently we started noticing a different behavior:
When selecting .mp4 files larger than ~200MB (e.g., 201MB+), the app fails.
On web (tested in Chrome, Edge, Brave — including clean sessions and incognito), the app becomes unresponsive or crashes right after selecting the file.
The issue happens before the upload process even starts.
On mobile devices, the file can be selected, but the upload fails when saving.
Files below ~200MB still upload normally.
Additional details:
This issue is happening across multiple applications (not app-specific).
It affects all users.
Google Drive storage is not an issue (we have sufficient space).
This behavior was not occurring before — uploads up to ~400MB were working in our tests.
We’ve already tried:
Clearing browser cache and using clean browser environments
Testing different networks
Testing across multiple browsers and devices
We tried uploading different videos with different sizes
We are attaching some short GIFs showing the behavior when selecting files >200MB.
Gif when selecting files < 200MB
Gif when selecting files < 400MB
Questions for the community:
Has anyone experienced similar issues recently with large file uploads?
Are you currently able to upload files >200MB successfully?
Has there been any known change in how AppSheet handles large files on the frontend?
Any insights or confirmations would be greatly appreciated.
Hello @sricse, we are investigating the issue and will revert back when we will have some updates.
Meanwhile, if you can raise a ticket for the same, it will be easier to follow up.
Hello @Steve, I am extremely sorry but I do not have any updates yet. The issue is still under investigation. I will look out for any progress on this issue and update here.
Hi @Shourya_Tomar, just adding that we’re hitting this exact same issue — uploads fail above ~200 MB. It’s currently blocking a workflow for us, so we’d really appreciate any update on the investigation, or a rough sense of whether a fix is expected vs. whether we should plan to architect around it. Thanks
Hello @Steve, Thank you for following up. I know you are waiting for an update, and I really appreciate your patience while the team finishes looking into this.
The team has been focused on some major core projects over the past few weeks and hence it is taking longer than usual for the resolution.
I am keeping an eye on this and will get back to you as soon as the review is done.
