When attaching a pdf to an email to be sent I am not able to open it and check it is okay. This has happened only since upgrading to Thunderbird 91.2.0 (64-bit) last week. I use Nitro Pro as my preferred pdf reader and this is associated in control panel.

I always check pdf's prior to sending to make sure it is correct.

As soon as I click on the pdf attachment the Microsoft App Store saying that "the app you're trying to install isn't a Microsoft-verified app..................", however, I am able to open pdf's with NitroPro that are attached to emails that I receive without a problem.
