Missing/Incomplete support of the EXT_buffer_storage (coherent memory) GLES extension

I'm trying to trace/replay of our game Dota Underlords which recently launched on Android (you can grab it free on the Play Store). I am using gapid-1.6.0 on Windows. When I capture a trace on Google Pixel 3 XL and try to replay it I see no framebuffer images and the "Report" tab says that each draw had GL_INVALID_OPERATION and a bunch of GL_OUT_OF_MEMORY errors making the replay unusable.

Attached is a trace from the Pixel 3 XL showing the problem.
