[BUG] Problem when adding signature image in Adobe Acrobat Pro DC v22

[Udube]

We have installed Adobe Acrobat Pro DC on all our user machines.

For the people with a license we let them log in so they can use the Pro features.
For the people without a license we let them use this version as a Reader.

This worked out great, but now we found out a bug.

With Adobe Acrobat Pro DC when adding a signature image I go to "E-Sign" > "Fill & Sign Yourself" > "Sign" > "Add Signature" > "Image" > Browse to the image signature (.PNG) > Click OK

And we receive a warning "You do not have access to this feature. Please contact your IT admin for more details." (Mind you that this is a FREE feature). When you click OK, you can still continue and add the signature to the document. But the signature is not being converted to one with a transparant background. See example:

I went ahead and installed Adobe Acrobat Reader DC and did the same thing.  "Sign" > "Fill & Sign" > "Sign yourself" > "Add Signature" > "Image" > Browse to the image signature (.PNG) > Click OK.
Now I (ofcourse) received no warning since this is already the free version, but more importantly, the signature image is correctly converted to a true signature stamp with a transparent background. See example:

This is in my opinion a real bug and should be fixed. The only solution now is to install the Reader version for all our users.. This would be a bummer since Adobe told we could use the Pro without signing in and be able to use the non premium features.

This issue could be better discussed at Acrobat forum. Moving it there

In addition, these forums are mainly meant for peer to peer discussion with very little Adobe staff participation. For bug reports the better place(where Adobe Engineering team looks, responds and picks issues for fix) to post would be

++Just curious,

Is this happening with a .png image that wasn't created with a transparent background?

If yes, then the bug seems to be related to an editing feature that tries to make the background transparent.

If that would be the case, what if the .png image  already has  transparent background?

Would you get the same error message?

This is happening with a PNG image without transparent background. Adobe normally would remove the background, but this is not the case for Adobe Acrobat Pro DC. 

I've just tested it with a PNG WITH transparent background, but even then, Adobe can't handle the transparent part and will show the checkered patern.

You ask if I get the same error message, but I never receive an error message. Just an incorrect warning that I'm trying to use a Pro feature. This same warning stays when using a transparent image.
