As @Ingo already wrote further above
In the version info for your phone it should show A.0118 and a security patch level of 2020-04-05 if you are really on the most recent version.
So please try to update to A.0118 first, which you should do anyway because it contains some important security patches. If you have a Vodafone SIM (or one from a provider that uses Vodafones network) try another SIM temporarily to receive the OTA.
Good luck!
