Synced Audio waveform not appears in timeline

OK:
DaVinci Resolve 19 Public Beta 3/M3 Max/Intel
Deleting cache does not help, Audio waveform appears in the media but not on the synced audio waveform timeline... Or it appears partially for short tracks. All tracks longer than 3 minutes have no waveform
Everything was fine in Beta 2
What else can I try? Any useful tips!!! Please!!!
Urgent work on the music video has stopped:(((

I can’t switch back to Beta 2, there are reasons

Yes - this is only relevant for Synced Audio waveform
If drag a waveform without synchronization from media on the timeline, the waveform will be displayed
But there’s no need, everyone always works to synchronize the sound!!!

You can report issues with version 19 in the Beta forum at the top of the Resolve page.
