Anyone notice Teams channel messages you're sending from python scripts, etc not actually reaching the destination channels in past 2 weeks?

Over the past few weeks we've noticed some automated messages we are sending to our teams groups using Python have not been reaching the destination channels after years of using Teams in this way. It has just been over the past 2 weeks or so. It's almost like they are trying to "spam filter" it somehow but we use this for notifications so we need them to not do that. Has anyone else noticed this?
