Hi Carson
Thanks your help. Yesterday I find the root cause that is a stupid error of not set target deploy to ios 12(by default it’s 13).
Getting over this issue, I still have two issues: 1) In Ipad sharing video or audio always stop under share screen mode. But in Iphone it’s not reproduced. 2)It often get stoped error, especially I touch web page based UI, example this one.
