basically it function well for a day,
but afterwards (after losing power or whatnot9) it would not longer function.
neither disney+ nor amazon vod could open stream.
for coreelec 21.2 nightly error like
opening stream> 1001 source 256
error <general>: AddOnLog: inputstream.adaptive: WV-CDM-Library Initialize: Failed to load library: /storage/.kodi/cdm/libwidevinecdm.so: wrong ELF class: ELFCLASS64

T:3971 error <general>: AddOnLog: inputstream.adaptive:GetStream (1001): Decrypter for the stream not found
T:3971 error <general>: CDVDDemuxClient::RequestStream - invalid stream
but i understand this error is related to CoreElec, wrong forum.
for LibreElec, it would not play video, just audio.
for CoreElec, it would play fine for Disney+ (small wideine download initially) and Amazon VOD (big Widevine update 1.3 GB) for some time, but afterwards no longer play at all.
