Closing this as resolved, possibly because all dependencies update on both SDK and App repositories, and it was not seen in the last PRs' check on CI.

Reopening this as it occurred in https://github.com/Electric-Coin-Company/zashi-android/pull/1408 in test_android_modules_wtf_no_coverage CI check again. Note that we are experiencing this only in the CI check.
