Google Play Billing Plan Upgrade/Downgrade with DEFERRED proration mode

In my Android application, we have multiple subscription plans, 1/2/3 months, which offer app features, for different durations, to users. User may switch between different plans during an active plan. E.g. suppose a user opts for 1 month plan. After 15 days of this, user may switch to 3 month plan. Billing for 3 month plan will only happen after the current plan i.e. 1 month period ends. We have credit card billing at the moment but now going to implement Google Play billing as well. For Google play, the deferred billing mentioned at https://developer.android.com/google/play/billing/subscriptions#change seems like the obvious solution to this use case.

val flowParams = BillingFlowParams.newBuilder()
    .setSubscriptionUpdateParams(SubscriptionUpdateParams.newBuilder()
        .setOldSkuPurchaseToken(purchaseTokenOfOriginalSubscription)
        .setReplaceSkusProrationMode(ProrationMode.DEFERRED))
    .setSkuDetails(upgradeOrDowngradeSkuDetails)
    .build();
val responseCode = billingClient.launchBillingFlow(activity, flowParams)

However, in my experimentation, I found that what I try to switch the plan for first time, the deferred proration mode works well. However, if I try to switch the plan once again during the first plan duration, the Google billing shows an error prompt.

According to Google Play developer support's response, received today, on same query;

The error occurs because there is a current limitation for the deferred proration mode. When there is a pending deferred subscription replacement, no new deferred replacement could be initiated until the previous one is applied.
