Re: How to get rid of notifications shown on support.ptc.com page
We have longer term plans and designs around Preference Management which expose the current Products / Roles selected in Onboarding.
Could you confirm that the stickiness issue you were seeing is now gone (or if still present, let us know the title of the alert you're seeing after a dismiss) ? We're able to see an item for your account in the "dismiss bucket" for the "PTC_Creo_Elements_Direct_20_1_3_0_now_available" alert on our side.
Please also let us know if you're seeing anything unexpected in future (i.e. not for the 3 products you've selected, and not a Service Alert), and we'll investigate.
