Google has updated its app testing requirements, reducing the minimum number of testers for closed tests from 20 to 12 for developers with personal accounts created after November 13, 2023. The new requirement states that these developers must conduct a closed test with at least 12 opted-in testers for a minimum of 14 consecutive days. Developers with business accounts are not affected by this change. The adjustment comes in response to criticism from indie developers who found the previous requirement challenging.
