Hi.
That's because PB 2021 is EOMM. This means that you cannot get support for free. You can of course get paid support, but this doesn't mean that appeon will provide a fix. This is what you could expect when a product reaches EOMM and you ask paid support:
When a version reaches the EOMM date, it will, however, no longer be generally supported by engineering. Specifically, Appeon will no longer provide any MRs for any software defects of the applicable software version, and EBFs may be provided under limited circumstances to customers that have paid applicable Premium Support fees.
This means that even in that scenario, solutions provided may be workarounds.
Of course you are right, the mail you received should state EOMM and not EOL. But as I understand it, EOMM is a special EOL state, where you can still get paid support, but should not expect fixes but help to solve a problem with workarounds, if possible.
Andreas.
