Hi Pavel,

Apologies if I miss out that this is a new issue.

Would it be possible for you to provide the following details in order for us to investigate the issue further?

• Sample project where the issue is reproducible and its steps to trigger the memory leak
• Is the issue was reproducible using our sample Ad Unit IDs?

Please use the "Reply Privately to Author" option to share the details privately.

Same issue here. 

Would you able to reproduce internally? Any solution?
