Remove the forced hashtag.
This is totally unprofessional. Do this for people who aren't already Adobe clients - but as a longtime Adobe CC complete subscriber - it pains me to have to push your products in my creative output. This is pretty basic stuff.
It sounds like you are referring to the watermark on Spark Post? This can be removed. You just need to tap on the watermark, share when the prompt is displayed and then the watermark will not longer be present on your designs. Hope that helps!
