rehctelf I had this issue, I had send in the same block 2 transactions from my reddwallet but only the first appeared in the browser wallet.
To sync the second one according to explorer I had to remove my seed and then import the seed back in order to read the addresses right.
It is a bug I think… If we have a refresh now button on the wallet I could avoid this. I didn’t try to close the chrome, but I thing that in theory it should also solve the problem.
