Our team needs a dedicated uploader button for non-image files. There already is one for images (the Add Media button) that we've managed to repurpose using Flow so that we can upload our .pdf, .xlsx, and .docx files, but this only works on the desktop version of PowerApps - on iOS it won't let you pick a non-image file. We're worried that a future update might kill our workaround and leave us unable to upload non-image files, and at this point our users will riot if that happens.
Please create a file uploader button - or at least an add file button - in PowerApps. It's very strange that you can effortlessly take and upload selfies using PowerApps but when it comes to uploading a simple PDF you have to devise a complicated workaround.
