We have 2 users who use Andorid Samsung S9 with new RingCentral App. They both are experiencing similar issue. When they are on an active cellphone carrier call and if someone tries to reach them on RingCentral phone they can see the incoming call from RingCentral Audio; however, when they click on Accept they get a message on their phone that "You are currently on an android phone call to accept this call (RingCentral Call) you will need to disconnect the current android phone call.

iPhone users don't have this issue. They are able to place active carrier call on hold to accept RingCentral calls and go back and forth. Does anyone know a workaround or fix for this?
