I am also having the issue that my Digi 150 infinite download speed has been capped as 5Mbps, even though I only used 100GB so far in the quota.

This only happen since yesterday, and my other postpaid Digi 80 plan is working fine with download speed 30Mbps.

This is ridiculous that Digi choose to capped the Digi 150 infinite user download speed as 5mbps. I just filed the report to Digi helpline and hope you all do the same too to file the report.
