I noticed a problem when I first tried the Strike app, (although this was a bug with the app itself, I'm sure) where I was able to withdraw funds to WoS, and the funds were both available to me on Strike and in the wallet the following day. (I was able to withdraw the funds again to another wallet.)
I gather from what you wrote:
You sent from Custodial wallet A (Strike) to Custodial wallet B (Wallet of Satoshi).
The transaction appeared to complete normally, but the next day you saw the funds in your Strike wallet again.
Did the transaction in Strike trx history disappear, or did it say failed or something like that?
Since you were neither the sender (that was Strike), nor the recipient (that was Wallet of Satoshi), there is nothing you (or we) can do to help further figure out where the issue was, other than you inquiring with one or both of those apps.
