I typically backup photos from my iPhone (7+, iOS 11.0.1?) to Google Photos. Typically it goes quite well; I connect my phone to wifi, and the photos (all of them), automatically upload to Google Photos.
Recently, I also purchased a Cannon t6 camera. After taking pictures with that camera, I transfer them to my phone. I do not resize them during the transfer. They are all shot in RAW but to my knowledge are changed to JPEG during the transfer.
Here's the problem, all of my other pictures in my camera roll just show up in Google Photos as soon as I open the app. The pictures from the t6 that were not resized do not show up. A quick Google search of this revealed that it could be due to size or formatting, I checked this by emailing one of the images to myself, it was less than 1MB (367KB) and it was JPEG.
I just updated the Google Photos app today and that did not fix the issue. I am in the process of doing an update to iOS 11.0.2. I also tried turning my phone off and back on, that did not fix the issue either.
Has anyone had this happen before? If so, how did you fix it?
