MarginNote 3 v3.7.12 unusable due to crashing on iPadOS 14.7.1

I just installed MarginNote 3 v3.7.12 on my 2018 iPad Pro 12.9” running iPadOS 14.7.1 an it has been crashing since the moment I installed it. I performed multiple forced restarts on the iPad Pro, defragmented MarginNote’s database, and cleared MarginNote’s buffer. It still continues to crash.

I will try to delete, then reinstalled MarginNote 3. Since MN3 was just installed today, I am skeptical that this will solve this problem.

This did not occur to MarginNote 3 when it was installed on my previous iPad Pro 12.9” (which was replaced by Apple due to a catastrophic failure).

In it’s current state (crashing endlessly), MarginNote 3 and my ongoing subscriptions are a waste.

Please help me resolve this issue and so I can continue my research.

Uninstalling then installing Margin Note 3 did not change (reduce) the frequency of crashes.

Update 21/26/08 1:22 PST
I appears the crashing is related to an ePub that I had added to a Study Group. Removing the ePub and replacing with the equivalent PDF appears (after limited use) to have resolved the crashing.

Thank you.
