Matomo Plugin "Page Performance" not working with Tag Manager?

HI,
when I click the nice “Open Performance Report” icon in the pages overview, the graph opens empty for every URL.
Do I understand it right that the “Page Performance” Plugin is only working with the “normal” JS tracker? Is there a possibility to get it working with Tag Manager? Or am I wrong and need to look for and fix another error?
Thank you in advance!
Best Regards,
Helge

Personally, I use MTM, and the page performance report works well on each page…
Which version of Matomo do you use?
Can you confirm that perf parameters are not sent to Matomo on page views events? see: Tracking HTTP API: API Reference - Matomo Analytics (formerly Piwik Analytics) - Developer Docs - v4

Thank you for your quick reply, which also gives me hope. yes, the corresponding parameters are transferred in the URL.
What else can I check to localize the error?

Then the problem seems come from the server itself.
I have no idea about this.
Somebody from the Matomo team, maybe?

Hi, I see we have the same issue.
Did you find any solution yet?

HI, no, unfortunately not…

Do you use the last version of Matomo?

yes, Matomo version 4.4.1

Did you try with different browsers?
Can you display the pageview request? eg. POST https://matomoserver/matomo.php?action_name=SAMPLE&idsite=1&rec=1&r=880377&h=16&m=14&s=23&url=http%3A%2F%2Fserver%2Fsample&urlref=http%3A%2F%2Fserver%2F&uid=TestUID&_id=19010a269c09b3fb&_idn=0&_refts=1629468863&_ref=http%3A%2F%2Fserver&send_image=0&pdf=0&qt=0&realp=0&wma=0&fla=1&java=0&ag=0&cookie=1&res=1920x1080&dimension1=Test&pv_id=2pJL1r&pf_net=0&pf_srv=365&pf_tfr=6&pf_dm1=1205

our link looks like this:

All other data appear in the system, only the performance values do not.
