ORB20 SIM PIN length

Few improvement proposals for the mobile setup app (Android) and possibly for the firmware of this ORBI LTE (ORB20) router: First I tried to install the router with the mobile app as it was recommended by Netgear and because the app has good rating. Everything went smoothly until the SIM PIN was asked. I used the five digits PIN which works perfectly eg. with my Google Pixel 4 and with Tplink Archer MR200 4G router. Mobile app gives ambiguous error message "Something went wrong. Please try again.". Needless to say, but new try of course does not help at all. Then I tried the installation with the web app. At the same point as before I got error message, but now with additional information that PIN has to be 4-digit code. OK, I took the SIM out and changed the PIN with my mobile phone to 4-digit code and after that I was able to complete the installation. It took in total more than one hour to find this solution. I guess others might have given up earlier and returned the product. Netgear: Please make corrections that allow the PIN code according to the standard defintions.
