Currently there is a limitation of uploading a file attachment size to max of 10 MB. SInce SPO can accept upto 250 MB per file in a list item, it makes sense to increase the attachment size in PowerApps to 250MB.
@gdavis53 it all depends on the problems you are trying to solve. We have been helping several clients implement PowerApps and they have been pretty happy with the solutions that were created. It's not appropriate for every problem, but it works great for many.
Thank you @FilipK for the update though going from October to aiming this year is less good news especially as this file size increase is already long time due ... Any reason for the delay (i.e. because of priorities or complexity) and what is the likelihood of releasing the update this year? Thanks!
Is there any ETA ? because this is major roadblock for our clients. ETA will decide whether they want to hold for this limitation or think of some other workaround for this. @FilipK
We are increasing the upload limit to 100MB but the planned October release date is in jeopardy. Still aiming for this year, I will update the thread.
