**Developer response:** Can you send an email to support@otubio.com. Do you have the latest version of the app? Please email us so we can solve whatever issue you are having.

### 3/5 — Warning of depletion of funds during call

*2020-06-23*

Please give the caller a heads up that there call is about to end because lack of funds. I’m tired of it hanging up on my father. I would like to end the conversation politely, please.

**Developer response:** Hello, we apologize for the inconvenience. The last minute remaining announcement was removed because most users considered it a disturbance. To prevent your call from disconnecting due to no balance, you can set up auto-recharge from your account on the website. This ensures you always have call credit and calls will not end due to no credit on your account. If you have any more issues, please email us at support@otubio.com or open a support ticket directly from the app. Regards.
