Hi Štêpán,
Thanks for responding.
Bear in mind I'm trying to do this with the PAID version of Cleanup. But it didn't allow me to share the app across multiple devices the way paid version of AMS does.
When I try to refresh the Cleanup purchase on my second device (using the same Google Store login) it doesn't make the necessary update. It asks me to purchase it all over again.
As mentioned, the premium version of AMS allows sharing under multiple devices as long as it's under the same Google Store account. And I definitely made sure it was under the correct Store account.
When I called into your CS phone line to voice my frustration, the agent I spoke with asserted that the paid Cleanup license couldn't be shared in the manner that premium AMS does.
So being told that, in addition to not being able to share the paid subscription of the Cleanup license, is what prompted me to post here.
