Offline App images problem

[ensosimon]

Hello all. I have created a solution with a table and a column with data type image. I do these steps as described in the Microsoft article. https://learn.microsoft.com/en-us/power-apps/mobile/offline-file-images
I can edit the other field without any problem. But when I upload an image on a mobile device, it is displayed in the forms but it is not uploaded to the table.
And there it doesn't matter if I am offline or online. Has anyone used this feature yet? The image is first displayed in the app but disappears after a short time.

Hi @ensosimon ,

I am glad to know you are using the offline functionality of Powerapps. As this feature is already in preview mode that's why It has some limitations including the mentioned problem. Here is the link and screenshot of what I found on on web about Offline Canvas App Limitations.

due to this, I can't recommend it for production or UAT but for learning purposes it's fine. 

If this is the answer for your question, please mark the post as Solved.
If this answer helps you in any way, please give it a like.

Thanks!

if you want to jump down the rabbit hole of offline images (like I have), one workaround I've found is to convert the image upload into base64 and then save the base64 value directly into a dataverse long text field (you may need to use several text fields and string manipulation to split the base64, the bigger the file size the bigger the base64string).

then, if you're uploading back to sharepoint, you'd use power automate to compose the base64 field strings together and convert to binary, or if you're just surfacing them again in power apps you can just put the base64 strings together with some string interpolation. you'll probably need this:

data:image/{[string interpolation used to get image file extension]};base64,

similar to the poster above me, i do not recommend going down this approach for production apps unless absolutely necessary. it is completely jerry rigged, prone to break at any moment, and extremely experimental -- but it does work

I have the same issue. When device is offline, I add a new record and update file column of another existing record. After that I turned on devices internet connection. A few minutes later, new record is synced normally with the file column but the existing record is not updated.

having spoken to a Microsoft technician about this issue, it looks like this is intended design and a limitation with the new offline images feature. you're probably not going to get much support from Microsoft either since its a feature in preview! we decided offline functionality in Canvas apps just isn't good enough for production usage and decided to put it on hold until it becomes more usable.
