I looked at what you posted. I don’t recognize the first crash. The second crash is the terrible libmonochrome crash. You are not alone. Usually, this is a playable ad with some nasty javascript. I don’t use StartApp or AdColony (the only two networks you have enabled).
The last StartApp version according to the changelogs for Appodeal is:
2.5.5 (June 20, 2019)
- Fix Ads CountDown view crash during size changes
- Fix issue with missing banners during animations
- StartApp updated to 4.0.2
StartApp has produced many versions since then and I am not clear what they changed since I can’t find the change logs. You might benefit from updating this library manually until it breaks Appodeal.
The last AdColony version according to changelogs for Appodeal is:
2.5.10 (4 November, 2019)
- AdColony updated to 4.1.0
Looking at changes since that version, I see that AdColony did address a webview issue with version 4.1.2. Manually updating AdColony up to that version might be beneficial if it doesn’t break Appodeal.
