BD shows email as plain text - Outlook, Thunderbird, WLM - last update ?

Daily I recieve lot of emails and yesterday (12.08.) started recieveing them (not all! from random senders) in plain text instead of html (or mime).
Some of my clients (who have BD installed) have also started complaining about this. I haven't found a solution yet, neither in antispam nor in encrypted web scan. I think it's the fault of the last update (?). When will this be resolved?

The issue has been reported by few users.

Is this a (known) bug?

Thanks.

Hi,

This is being investigated as we speak. We've seen several reports on the forum, but also on other forums and most certainly the Support teams have had their fair share, so the situation is being addressed by the development teams.

Thanks!

All emails coming into my main/default (POP3) account on Outlook 2021 and on Windows 10 Pro became unreadable on Monday 11 August. All have subject line removed and display X-VadeSecure-score, X-SNCR-PAB, X-OWM-DKIM etc. Text in emails is all coded. My other email account (IMAP) on Outlook 2021 was unaffected. There is no issue with my ISP - I checked with them. Disabling email/spam protection in Bitdefender and the Bitdefender Add-In on Outlook 2021 did not fix the issue for me. However, uninstalling Bitdefender completely has fixed this issue and I can now read any new emails coming in. I would like to reinstall Bitdefender but not if it is going to cause further issues. I switched over to Windows Security as a temporary measure. I did report the fault to Bitdefender yesterday and I now see that other users have been affected too.
