Appears this is still an issue on the current public release of PMS. Version 22.214.171.12435. Daughter who lives in another state experienced this on Xbox one and Android phone for a few hours until it finally resolved itself on Saturday evening. Meanwhile another in the same house was able to stream on a completely different device without issue, Roku, but that stream had started 30 minutes prior and seemed to be unaffected.
Unfortunately I wasn't able to get to the logs till this morning and they were overwritten by yesterday's and this morning's. I thought PMS kept several days worth, but I guess that has changed? Is there a way to set the log file parameters?
