Since installing a Zoom update a few months ago, I cannot hear anything from others on my Zoom meetings. They can hear me but I cannot hear them. I have full audio on everything else I use my laptop for. I have done all the recommendations in articles, etc. more than once to no avail. Help Please!

Thank you!

When I created a new meeting (reoccurring) and loaded the Polls, the Polls appear in the reverse order in which I loaded them into the meeting.  This never happened in the past.  How do I have the Polls appear in descending order (i.e. Poll 1, Poll 2, Poll 3, etc.).  Also, the Polls I loaded into this new meeting now appear in all my previously created meetings, how do I stop this?  Thanks!

I am getting this message, "You are sold to a country that is ineligible for this currency," while trying to purchase an addon. How do I fix this?

I am trying to purchase an addon, and it is urgent for a meeting to happen in the next 12 hours. Please help.

I tried to change the billing settings to INR but it doesn't work

Normally during Zoom meetings over my iphone just dialing the meeting phone number to join a zoom meeting not using Zoom app. The host controls mute and unmute. But to make sure background noise on my end isn’t detected l also mute my dial pad. However, the last couple weeks 

l can’t hear 06 you’re muted or unmuted. Even when my phone dialpad isn’t muted.  Also l can hear the participants but they cant hear me even though the microphone on my phone dial pad is unmuted. I’m worried that the group may have heard background conversations and i’ve been permanently muted by the host. Can anyone confirm if background noise can still be heard if you have muted your phone dialpad microphone? Thanks
