Every day after my first boot up I have to re-assign my PTT bind for team voice (capslock), but not my PTT bind for party. What can I do?
Hmm, I suggest getting in touch with riot support, (https://support-valorant.riotgames.com/hc/en-us/) they can better help with your issue.
However I believe you can change your voice settings to automatic voice. Whilst it may not be wanted, it can be a temporary fix.
Hope I helped!
