(iOS only) Black empty screen in conference on repeated change of participants list

iOS SDK (3.8.1 and earlier) gives black screen when I try to re-enter in the existing conference with 2 participants (I’m the third one).

In the log we have TypeError: undefined is not an object (evaluating 'A.id') It is from Thumbnail.js, line 130

It seems that sometimes participant is undefined in the context of function Thumbnail(props: props).

If we start SDK the first time then it’s OK. But if we exit from conference and back again then we can get the black empty screen. It may even occur if some one from other participants exit and enter again (black screens will appear on iPhones in conference).

Also systematically after every re-enter to any conference iOS has multiplication of other participants. At the same time in web in android we have current participants list.

All of this seems to be local iOS sdk problem, maybe due to local cache.

This problem arises only with token authorisation. There are no problems with guest access.

@saghul Nope, I had two PRs of avoiding those undefined, then I found out the problem is actually mixing selectors and connect function and fixed that on the web, by moving the problem component to use connect, so I would guess same is happening and there and needs to be fixed the same way by not mixing both approaches when the components are looking up participants by id.
