Frankly as for now since 2 weeks I do not have any issue with any apps excepted that the fingerprint/face ID do not work with them ... (My network issue was my router...)
May be you have to do a factory reset and look at your installed apps ...
is there an OTA update for this version? I am STUCK with 20190912_20200306-1721 and Wireless Update says my "device software is currently up to date" How do I update without Windows PC?
