Adding an Adafruit LTC 4311 Active I2C terminator resolved the issue. May not be your problem but it is worth a try.
Hi. Thank you for the suggestion, I added the LTC 4311 I2C terminator to see if it might work and re-tested the system. In this case it didn’t resolve the issue.
I hope it is a minor software incompatibility in the change from OP3 to OP4 which can be found soon. I will try using an ADS1015 in the meantime and see if those are compatible with OP4.
I will report back with my findings, don’t hold your breath though it could take me some time.
