Snapshot download failed on Ring Doorbell Pro

I have a Ring Doorbell Pro that will not save snapshots. I am able to save videos. I am using the newest Android version of the Ring app version 3.31.0 on my Samsung Galaxy S20 Ultra and Samsung Tab 7+. Both are listed as Authorized Client Devices in the Control Center. I have activated the Snapshot feature in the device settings. The firmware says that it is up to date though I don't know the firmware version. My RSSI varies from 60-64. I have searched for a solution, but have not had any luck finding one. Thanks in advance for your help in solving this problem.
