I upgraded to android 11 last night and now have the same issue. Sim keeps dropping out. However with deselecting 4g... it is stable... how do we fix this?

Hi, I am having the same issue by the look of it. The networks drop out continually, both Telstra (SIM 1) and Optus (SIM 2).
Only started happening after the latest update.
Update: This has been while both SIMs were in 2G/3G/4G. I've since changed the settings to see if it narrows down to a specific SIM, and SIM 1 seems to be the issue. When SIM 2 is set to 2G/3G/4G it is OK, but as soon as SIM 1 is set that way it has problems. Setting this on 3G it seems stable.

Can someone help?
Ben
