Hello,
I understand the problem. Hadn’t thought about it.
As an admin, you can cancel a user’s transaction at their request from Wallets -> Transactions.
A user unfortunately cannot cancel a transaction at the moment. It is not feasible for me to develop a solution for this right now. Perhaps something for later on, I am adding it to the backlog for after the wallets6 release.
In the mean time there is this setting:
“Wallets” -> “Cron job” -> “Old Transactions” -> “Cancel old unconfirmed/pending transactions”.
The value is in minutes. For example, if you set it to 60, then any unconfirmed/pending transactions will be cancelled when they are older than 1 hour.
Hope this helps.
with regards
