It seems Tipsi will not update the stripe module, as there is an official library from Stripe Itself.
I'm using stripe for Google pay and Apple Pay only. Even though I haven't used the Card payment, It is mandatory to update to 16.9.0/16.10.0 in order to prevent rejection.
One Good Way: Open Android Studio -> Go to Build.gradle of tipsi-stripe -> Update Stripe SDK to 16.9.0 (it will show you the tooltip dialog box to update to 16.9.0, as you hover over implementation 'com.stripe:stripe-android:10.4.6' line).
Click Sync now (in the header part of build.gradle)
Go to tipsi-stripe -> java ->com.gettipsi.stripe
