My conversion limit on WhatsApp is not increasing even after I verified my Facebook Business Manager.

This is because Meta's validation changed and it's not (just) based on BM verified anymore.

Automatic Scaling is not working. Sent over 5K business initiated messages in last 7 days, mainained high quality, waited almost 3 weeks fulfilling all the criterias for an increase from 1K to 10K. But still not increased.

Same issue here. It seems to b stuck at 1000 / 24 hours. I had no option but to register another phone number for another 1000.

Same for me... and there is not a channel for address this issue.
