Feedback test should be done, you don’t want any leakage from your ear molds, just turning up feedback manager is not the best way, also your audiologist should do REM to see if they can find the actual frequency that’s causing the issue, but again the molds need to be a tight fit for any increase in gain.
Again a simple adjustment issue in Aventa, make sure you take your smartphone with you and check after each adjustments.
You don’t mention the App, are you using one, the older ReSound Smart App I use with the Linx2 should be ok with the Enzo, you don’t mention which phone you use iPhone or Android with phone clip.
All these issues you need to talk through with your Audiologist, the firmware update could well help with streaming so make sure you get it done, but usually its just bug fixes as such.
