Use Digital Certificate on Adobe Acrobar IOS version

Hi All,

Firstly I sent and imported my Digital Certificate via email to my iPad. Then I configure the Digital Certificate correctly since I can see it looking: Settings > General > Profiles & Device management.

Then, when signing a PDF I'm not able to find the option "Certificate" for signing a PDF document on Abode Acrobat app.

I also tried with Adobe Fill & Sign app with no result.

In both cases I'm only able to draw the signature, however I can't stamp my digital certificate.

I have also MobileIron as MDM, could it be causing the issue?

Thanks in advance...
