Today I tested on the Mumbai Polygon network.
Several times I could not complete the test.
Transactions were confirmed for a very long time, I performed tasks for several days.
Especially when I made a deposit in the baskets, and the same with the withdrawal.
Also, error code 429 often got out when opening limit orders in margin and spot trading, but rather the reason was that it was necessary to change the price of a limit order.
Also, nothing is displayed in the transaction history in the application. It looks like it's not just me.
In general, an interesting tool for trading and investing. But too long waiting for confirmation of transactions.
