Hi yitwail,
Welcome to Affinity Forums :)
Thanks for your report and file. The text was imported but it was positioned incorrectly (outside of the canvas on the top left). To find it zoom out a little to see the area outside the canvas, change to the Move tool and select the text from the Layers panel. I'm also able to reproduce the problem of layers in slide 2 being partially visible (depends on the zoom level). I'm logging both issues to be looked at.
Exporting in Affinity isn't the same as Photoshop's 'Save for Web' feature. The whole point of 'Save for Web' is to optimise images for the web by removing a lot of useless metadata from the images like camera model, time, white balance, etc. This reduces image file size dramatically making it optimal for a web designers and developers.
Exporting JPEG files with Affinity Photo seems to reduce the file size more than Photoshop's 'Save for Web' feature.
But Photoshop's 'Save for Web' feature reduces a PNG file by roughly 30% more than exporting with Affinity Photo.
It would be great to have a similar feature in Affinity so users can preview the image as they're optimising it and get a similar file size to one that's exported from Photoshop using 'Save for Web'.
