Native ad crash in 2.1.7 #715

Closed ValentinPostindustria closed 7 months ago

ValentinPostindustria commented 7 months ago

Describe the bug Native ad without impression trackers crashes the app. It seems this happened after the PR merge #705.

Additional context It happens when adm doesn't have eventrackers field and imp_size array is null.
