ERC20 tokens swap widget refresh issue

[farman13]

I’m facing an issue on mobile web. When swapping two ERC-20 tokens on the same chain, the flow behaves as follows:

• Token approvals complete successfully
• The final transaction is submitted and confirmed on-chain
• Inside the widget, the status remains “Pending” for several minutes (I waited ~5 minutes)
• After refreshing the mobile web application, the widget then shows “Swap Successful”

So the swap is actually successful on-chain, but the widget UI does not reflect the completed state in real time on mobile unless the page is refreshed.

Could you please help clarify:

• Why this happens specifically on mobile web?
• Is this a known issue with route execution or event listeners on mobile browsers?
• Is there any recommended configuration, callback, or workaround to ensure the widget reflects “Swap Successful” immediately without requiring a refresh?

@farman13 We’re looking into this. Thanks for your patience, and please avoid tagging the entire team. Response times were a bit slower due to the holidays.

@farman13 Thank you for reporting this issue.
One possibility is that Android Chrome throttles JavaScript timers in background tabs (for battery optimization), which could affect status polling when switching between wallet and browser apps.

This behavior is documented here:
https://developer.chrome.com/blog/timer-throttling-in-chrome-88/

We couldn’t reproduce this issue on iOS Safari or Chrome. As a workaround, we could suggest adding a warning for Android users (for example: if the status does not update, please refresh the page).

Does this happen every time, or only intermittently?
